Abstract:
Oxabicyclic alkenes can react with electron-deficient terminal alkynes in the presence of a gold catalyst under mild conditions, affording the corresponding addition products in moderate yields. When using alkynyl esters as substrates, the (Z)-acrylate derivatives are obtained. Using but-3-yn-2-one (ethynyl ketone) as a substrate, the corresponding addition product is obtained with (E)-configuration. The proposed mechanism of these reactions is also discussed.

Full text
Abstract:
This thesis focuses on the asymmetric reduction of N-protected derivatives of (3S)-3-amino-1-chloro-4-phenyl-2-butanone to their corresponding diastereomeric alcohol products, which are key intermediates in the synthesis of HIV protease inhibitors. Although the stereoselective synthesis of the (S,S) alcohol product is easily achieved, preparing the (R,S) diastereomer is much more challenging. I investigated three diastereoselective reduction processes: 1) Meerwein-Ponndorf-Verley (MPV) reduction, 2) asymmetric transfer hydrogenation, and 3) boron reducing agents. The diastereoselectivity of the MPV reduction still favored the (S,S) product; however, I discovered a significant rate enhancement when the standard catalyst (aluminum isopropoxide) was replaced with aluminum tert-butoxide. Many reaction variables were investigated in the asymmetric transfer hydrogenation reaction and the diastereoselectivity was improved to give a ratio of the desired (R,S) diastereomer to the undesired (S,S) alcohol of 9.5:1. Using chiral oxazaborolidine catalysts, an unprecedented (R,S) to (S,S) ratio of 9.5:1 was achieved. Finally, I investigated the effect of the N-protecting group on the stereoselectivity of the reduction. When the original boc-protecting group was replaced with a phthalimide group, the diastereoselectivity of the MPV reduction was reversed to favor the desired (R,S) product.

Full text
Abstract:
In the solid state the rotation of a methyl group is hindered by a potential barrier and at low temperature the rotational motion is characterised by quantum tunnelling. The Pauli Exclusion Principle imposes constraints on the allowable eigenstates of the methyl rotor and leads to a combination of spatial and spin variables. The characteristics of these quantum tunnelling states, labelled A and E, are explored experimentally and methods are investigated for creating prescribed non-equilibrium states. We will investigate and explore the tunnelling polarization associated with the A and E tunnelling-magnetic levels by means of field-cycling NMR. Secondary rf irradiation is used to drive A-E and E-A transitions associated with NMR tunnelling sidebands. This polarization is then transferred to the 1H Zeeman system at a field-dependent level-crossing where the methyl tunnelling frequency equals one or two times the 1H Larmor frequency. The level-crossing contact is a necessary step since the tunnel temperature cannot be measured directly with a pulse. A new pulse sequence is described and the resulting spectra are analogous to the solid effect and dynamic nuclear polarization. Therefore we assign the phrase ‘dynamic tunnelling polarization’ to describe the experiments. Two samples are studied in depth, methyl ethyl ketone and acetophenone which have tunnel frequencies of 495 and 1435 kHz respectively. The experiments investigate the phenomena as a function of a variety of physical parameters in order to determine the fundamental physics.

Thesis, McGill University, 2006. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=103015.

Full text
Abstract:
Diacetyl (2,3-butanedione) is an important flavour active, oxidative compound that has significant impact on cellular health as well as financial impact in industrial fermentations. The presence of diacetyl in certain fermented beverages, such as beer, results in an unpleasant butterscotch-like flavour and its concentration needs to be reduced by yeast to below the taste threshold prior to filtration and packaging. This results in significant process inefficiency. Furthermore, diacetyl negatively impacts cellular health and has been associated with neurodegenerative diseases and general cell aging amongst others. The reduction of this compound is therefore essential for cellular health.
Several yeast cell enzymatic mechanisms responsible for diacetyl reduction were identified and characterised, including Old Yellow Enzyme (OYE) isoforms and D-Arabinose Dehydrogenase (ARA1). OYE isoforms displayed different micromolar affinities and catalytic turnover rates for diacetyl and catalysed diacetyl reduction in a biphasic manner. ARA1 catalysed diacetyl reduction in a monophasic manner with a millimolar Michaelis constant.
Knowledge gained in these studies was applied in investigations of diacetyl production and reduction in industrial brewing operations and the enzymatic systems further exploited for the development of a novel enzyme based assay to determine diacetyl concentrations in beer samples. Concentrations as low as 0.2 muM were detectable with high repeatability.

Abstract:
La production mondiale de solvants représente environ 28 millions de tonnes, dont 5 millions en Europe. L’industrie des peintures et des revêtements en est la principale consommatrice (46 % des solvants produits). Dans ce domaine, les solvants les plus utilisés sont l'acétate d'éthyle, l'acétate de butyle et la méthyl éthyl cétone. Ces molécules sont actuellement synthétisées industriellement à partir de substrats d’origine pétrochimique en présence de catalyseurs homogènes et dans des conditions énergivores. Afin de réduire l’impact environnemental des peintures et revêtements, la substitution de ces solvants issus du pétrole par leurs équivalents bio sourcés a été étudiée dans le cadre du projet européen ECOBIOFOR (FP7/2007-2013/Grant Agreement no 605215), dans lequel se sont inscrits ces travaux de thèse. Ainsi, l’objectif de cette thèse a été de développer, à partir de synthons renouvelables, des procédés de production de ces trois solvants simples à mettre en oeuvre, peu coûteux et respectueux des principes de la chimie verte. Pour la production des acétates d’éthyle et de butyle, deux voies de synthèse ont été étudiées en présence d’une résine échangeuse d'ions comme catalyseur hétérogène. La première voie utilise de l'acide acétique et l’alcool biosourcé correspondant (éthanol ou le butan-1-ol); la seconde met en jeu l’anhydride acétique à la place de l’acide acétique. Dans ces synthèses, quatre résines ont été testées. Des études cinétiques et thermodynamiques ont permis de choisir la résine la plus performante et les conditions de réaction les plus adaptées. Cette étude a finalement permis de proposer un procédé de coproduction des deux acétates efficace et innovant dans lequel la purification des acétates est facilitée, la production de déchets et coproduits est réduite et le recyclage de la résine est possible. L'évaluation des performances des acétates synthétisés dans des formulations de laques nitrocellulosiques et de vernis polyuréthanes a permis de montrer que ces molécules répondent au cahier des charges en terme de séchage, viscosité, formation de film, brillance et adhérence. Enfin, le bénéfice environnemental du processus de coproduction a été mis en évidence par le calcul des métriques de la chimie verte et l'analyse du cycle de vie des esters produits. De plus, l'influence de l'origine des alcools, biosourcés ou pétrochimiques, sur l’impact environnemental a été évaluée. L’impact sur le changement climatique est réduit avec l’utilisation des synthons bio-sourcés. Pour la synthèse de la méthyl éthyl cétone, nous avons décidé d’étudier la réaction de décarboxylation de l’acide lévulinique, molécule plateforme biosourcée disponible et peu coûteuse. Contrairement au principal procédé industriel qui repose sur la déshydrogénation du butan-2-ol d'origine fossile, la méthode développée dans ces travaux utilise des conditions plus respectueuses de l’environnement puisqu’elle est réalisée dans l’eau en présence de persulfate de potassium et d’un sel d'argent à une température raisonnable (100°C). L'évaluation du rôle de chacun des réactifs a permis de proposer un mécanisme réactionnel complexe de cette synthèse. L'étude de l’évolution des espèces en phase solide réalisés par diverses analyses spectroscopiques (RMN du solide, DRX, XPS, AES et MEB) a permis de mettre en évidence les espèces impliquées dans la décarboxylation et finalement de proposer une méthode permettant d’obtenir des conversions et des rendements élevés
Global solvent production accounts for about 28 million tonnes, including 5 million tonnes in Europe. The paint and coating industry is the main consumer (46% of the solvents produced). In this sector, the most used solvents are ethyl acetate, butyl acetate and methyl ethyl ketone. These molecules are currently synthesized industrially from petrochemical substrates in the presence of homogeneous catalysts and under energy-consuming conditions. In order to reduce the environmental impact of paints and coatings, the substitution of these fossil-based solvents by their bio-based equivalents has been studied in the framework of the European project ECOBIOFOR (FP7/2007-2013/Grant Agreement no 605215), in which this thesis work was inscribed. Thus, the objective of this thesis was to develop production processes for these three solvents that would start from renewable synthons and would be simple to implement, inexpensive and respectful of the principles of green chemistry. For the production of ethyl and butyl acetates, two synthetic routes have been studied in the presence of an ion exchange resin as a heterogeneous catalyst. The first route uses acetic acid and the corresponding bio-based alcohol (ethanol or butan-1-ol); the second involves acetic anhydride instead of acetic acid. Kinetic and thermodynamic studies have led to select the most efficient resin and the most suitable reaction conditions. This study has finally allowed to propose an efficient and innovative coproduction process for the two targeted acetates in which their purification is facilitated, the production of waste and co-products is reduced and the recycling of the resin is possible. The evaluation of the performance of the synthesized acetates in nitrocellulose lacquer and polyurethane varnish formulations has shown that these molecules meet the specifications in terms of drying, viscosity, film formation, gloss and adhesion. Finally, the environmental benefit of the co-production process was highlighted by the calculation of green metrics and the life cycle assessment (LCA) of the produced esters. Furthermore, the influence of the origin of alcohols (bio-based or petrochemical) on the environmental impact was evaluated. The impact on climate change is reduced through the use of bio-sourced synthons. For the synthesis of methyl ethyl ketone, we decided to study the decarboxylation reaction of levulinic acid, which is a bio-based platform molecule available and inexpensive. Unlike the main industrial process, which relies on the dehydrogenation of butan-2-ol from fossil origin, the method developed in this work uses conditions that are more respectful of the environment since the reaction is carried out in water in the presence of potassium persulfate and a silver salt at a moderate temperature (100°C). The evaluation of the role of each of the reagents allowed us to propose a complex reaction mechanism for this reaction. The study of the evolution of the solid phase species carried out through various spectroscopic analyzes (SSNMR, XRD, XPS, AES and SEM) made it possible to highlight the species involved in the decarboxylation and finally to propose a method to obtain high conversions and yields

Abstract:
The production of packaging goods for cement is one of the most important industries, contributing to income of many workers. Production activities, however, cause air pollution and health risk. The study was conducted to assess air quality and health risks of workers through air quality data and interviewing employees from 2016-2017 at a packaging production factory, Can Tho city, Vietnam. The findings indicated that temperature and noise exceeded the national technical regulations (QCVN 22-26: 2016/TT-BYT) while the humidity, wind speed, light, respirable particles, toxic gases (benzene, toluene, methyl ethyl ketone (MEK)) were in accordance with the national standards for occupational health and safety (Decision 3733/2002/QĐ-BYT). However, health risk assessment showed that long-term exposure in this factory would result in severe impact on health of workers due to indoor air pollution. The non-cancer risk caused by benzene, toluene and MEK for workers in the working sections such as printing, film coating, weaving, spinning and pasting was expected to cause serious impact on workers’ health. The cancer risk (benzene) index was in the range of 1.3 x 10-5 to 7.7 x 10-4 and averaged at 3.3 x 10-4. The study clearly showed that benzene greatly contributes to serious workers’ health effects. Appropriate protection measures such as treatment of air pollutants, regular health check, wearing protective clothes should be implemented to mitigate impact of indoor air pollution at the factory. More importantly, it is necessary to reconsider the standard values of benzene, toluene, methyl ethyl ketone to ensure health of workers.
Công nghiệp sản xuất bao bì xi măng thuộc lĩnh vực ngành xây dựng là một trong những ngành công nghiệp quan trọng, đã góp phần mang lại nguồn thu nhập cho nhiều người lao động. Tuy nhiên hoạt động sản xuất cũng gây ra những vấn đề về ô nhiễm môi trường không khí và rủi ro sức khỏe. Nghiên cứu được thực hiện nhằm đánh giá mức độ ô nhiễm môi trường không khí và đánh giá rủi ro sức khỏe của công nhân thông qua số liệu chất lượng môi trường không khí và phỏng vấn trực tiếp người lao động trong khoảng thời gian từ 2016 - 2017. Kết quả nghiên cứu cho thấy nhiệt độ, tiếng ồn vượt qui chuẩn cho phép (QCVN 22-26:2016/TT-BYT) trong khi độ ẩm, tốc độ gió, ánh sáng, bụi hô hấp, hơi khí độc (Benzen, toluen, methyl ethyl ketone) đạt chuẩn cho phép theo tiêu chuẩn vệ sinh an toàn lao động (QĐ 3733/2002/QĐ-BYT). Tuy nhiên, kết quả đánh giá rủi ro sức khỏe cho thấy công nhân làm việc lâu dài sẽ bị ảnh hưởng nghiêm trọng đến sức khỏe do ô nhiễm không khí. Rủi ro không gây ung thư do benzene, toluene và MEK gây ra đối với công nhân ở từng khu vực có thể gây ảnh hưởng nghiêm trọng đến sức khỏe công nhân làm việc ở các khu vực sản xuất như in, tráng màng, dệt, kéo sợi và dán. Benzene gây rủi ro ung thư với xác suất từ 1 đến 7 người trong 10.000 người trong quá trình làm việc lâu dài tại nhà máy. Nghiên cứu cho thấy benzene đóng góp rất lớn vào khả năng gây ảnh hưởng nghiêm trọng đến sức khỏe công nhân. Môi trường không khí bên trong nhà máy cần được cải thiện hơn nữa đồng thời tuyên truyền nâng cao ý thức công nhân thực hiện nghiêm túc bảo hộ lao động, tổ chức khám sức khỏe định kỳ cho công nhân. Quan trọng hơn là cần điều chỉnh lại các giá trị qui chuẩn để đảm bảo an toàn sức khỏe cho công nhân đang làm việc tại những nơi có sự hiện diện của khí độc như benzene, toluen, methyl ethyl ketone.

Abstract:
Chapter 1 outlines the potential application of metal alkynyl complexes and then describes the different methods in the literature for the synthesis of alkynyl, poly-ynyl and homo- and hetero-metal complexes. Their chemistry will then be discussed. This Chapter concludes with an outline of the work to be described in the remainder of the thesis. Chapter 2 describes a series of complexes containing a new tricyanovinylethynyl (3,4,4-tricyanobut-3-en-1-ynyl) ligand obtained by direct substitution of a CN group in tetracyanoethene by ethynyl complexes M(C=CH)(PP)Cp' [M = Ru, Os, (PP)Cp' = (PPh₃)₂Cp; M = Ru, PP = dppe, Cp' = Cp, Cp*]. The reactions proceed in higher yield as the metal environment becomes sterically larger and more donating; the normal [2 + 2]-cycloaddition / ring-opened product M{C[=C(CN)₂]CH=C(CN)₂}(PP)Cp' is also formed in some cases. The diynyl Ru(C=CC=CH)(dppe)Cp* reacts with tcne to give only the ring-opened adduct Ru{C=CC[=C(CN)₂]CH=C(CN)₂}(dppe)Cp*. Protonation of Ru{C=CC(CN)=C(CN)₂}(dppe)Cp* (10) afforded the vinylidene. A second transition metal fragment {MLn} [{MLn} = Ru(PPh₃)₂Cp, M'(dppe)Cp* (M' = Ru, Os), RuCl(dppe)₂] can be added to the CN group trans to the first. Compound 10 ready undergoes substitution of the 3-cyano group by nucleophiles. Some unexpected rearrangements and formation of O- and N-heterocyclic compounds were also found. Chapter 3 describes reactions between 1,2 dichlorohexafluorocyclopentene and Ru(C=CH)(dppe)Cp* (1) or Ru(C=CC=CLi)(dppe)Cp* which give Ru(C=C-c-C₅F₆Cl-2)(dppe)Cp* (36) and Ru(C=CC=C-c-C₅F₆Cl-2)(dppe)Cp*, respectively. Ready hydrolysis of 36 to Ru{C=C[c-C₅F₄Cl(O)]}(dppe)Cp* occurs, which can be converted to Ru{C=C(c-C₅F₄Cl[=C(CN)₂])}(dppe)Cp* by treatment with CH₂(CN)₂ / basic alumina. The cyano-fluorocarbon ligand in the latter is one of the most powerfully electron-withdrawing groups known. Chapter 4 describes the three methods of synthesising heterometallic carbon-chain complex {Cp*(dppe)Ru}C=CC=CC=CC{Co₃(μ-dppm)(CO)₇} (40), in two examples showing the first examples of Ru{(C=C)xI}(dppe)Cp* (x = 1, 2) being used in a cross coupling reaction with Ph₃ PAu(C=C)(₃-x)C{Co₃(μ-dppm)(CO)₇}. The reactivity of 40 with PPh₃, MeOTf, tcne, tcnq, Fe₂(CO)₉, NiCp₂ and Co₂(CO)₈ took place on either the C₈ bridge or on either metal centre. Chapter 5 discusses the reaction of 1 with oxalyl chloride which gave {Cp*(dppe)RuC=C}₂CO (52). This complex can be methylated to give [{Cp*(dppe)RuC=C}₂C(OMe)]OTf, which in turn can be protonated to the dication. Knövenagel condensation of 52 with CH₂(CN)₂ gave {Cp*(dppe)RuC=C}₂C{=C(CN)₂}. The reaction of 1 and bis(2,4-dinitrophenyl) oxalate afforded {Cp*(dppe)Ru}{c- C=C[C₆H₃(NO₂)₂]C(O)C(O)O}. The transmetallation reaction of {(Ph₃P)AuC=C}₂CO and RuCl(dppe)Cp unexpectedly gave the cyclic complex [1,4-{Cp(dppe)Ru}₂{c- COC(OMe)=CHCCH}]PF₆. Chapter 6 gives an account of the electrochemistry of many of these redox-active compounds and examines the UV-Vis absorption of the more polarised compounds. Some discussion of the various observed trends is presented. There is also a future direction of this chemistry given at the end of this work.

Abstract:
Maine Energy Recovery Company is a waste-to-energy facility, firing refuse-derived fuel (RDF) in two B&W boilers to produce steam which is used to generate 22MW of electricity. As part of its on-going effort to study odor generation and enhance their odor control system, Maine Energy discovered that a greater quantity of volatile organic compounds (VOC) are generated by the waste itself than had previously been estimated. The VOCs that were found are primarily light alcohols, such as methanol, ethanol, and butanol, along with compounds such as acetone, methyl ethyl ketone (MEK), benzene, toluene, xylene, and others. These compounds are generated from the operation of diesel-fueled equipment in the facility’s tipping building, and from the decomposition of the waste itself. The VOC generation also has a strong seasonal component, where generation is highest in the warmer summer weather, and lowest in the depths of winter. In the summer of 2005, Maine Energy undertook a pilot scale study of VOC control using a proprietary concentrator technology from Munters Corporation, Zeol Division of Amesbury, Massachusetts. A scaled-down version of their rotary zeolite concentrator was employed at Maine Energy over a six week period from July to September 2005. Numerous samples were taken at the inlet and outlet of the device, and several extended tests were conducted using Fourier-Transform Infrared (FTIR) technology to search for specific organic compounds. The results showed that the device reduced VOC, as well as odors, by approximately 85%, without the benefit of extensive fine-tuning of the device or the process during this limited run. The testing also revealed the need for extensive particulate removal at the inlet to the device, which would have a significant effect on cost efficiency.

Abstract:
Odor control is a frequent issue at facilities that process municipal solid waste. Even waste-to-energy facilities, which are typically operated under “negative pressure,” may be less than 100% effective at preventing the occasional release of odorous emissions. When odors travel off-property to nearby residents and businesses, the tangible exposure often elicits concerns about the specific chemicals responsible for the odor and the potential for the emissions to affect public health. However, because the gaseous compounds that may lead to objectionable off-site odors are generally different than those that might result in adverse health effects, conditions of odor and risk are not as closely linked as is sometimes assumed. While odors can be assessed through personal observations, the assessment of risk requires detailed knowledge of the composition of the emitted gases. The gas produced from the aerobic decay of municipal solid waste contains a different mix of chemicals that are not as well characterized than gas produced from the anaerobic decay of waste in a landfill (which has been analyzed by the U.S. EPA and others). Air samples were recently collected from the tipping floor of a waste-to-energy facility, analyzed for chemical composition, and evaluated for their potential to lead to off-site health risks. The composition of the gas was found to be similar to published data from other MSW handling facilities, and includes both basic hydrocarbons and some EPA-designated Hazardous Air Pollutants. Thirty-two different volatile organic compounds were detected. Ethanol was found to be the most prevalent compound, almost two orders of magnitude greater in concentration than other chemicals. Additional compounds identified in the gas samples include (in order of abundance) methyl ethyl ketone, acetone, sec-butanol, isopentane, acetaldehyde, butane, isopropyl alcohol, limonene, and 1-propanol. A case-specific atmospheric dispersion of the gases was modeled to predict off-site concentrations much smaller than levels known to cause adverse health effects. Based on odor characteristics of the gas, generically extrapolating the study to other settings suggests that short-term odorous conditions due to MSW management facilities (waste-to-energy facilities, transfer stations, etc.) do not typically correspond to significant long-term health risks.

Abstract:
Serotonin (5-HT) stimulates prostacyclin (PGI2) production by bovine aortic smooth muscle cells in culture via 5-HT2 receptors (1). These cells express a synthetic phenotype (2), whereas the majority of the smooth muscle cells in the media from adult arteries are in a contractile state. We have now shown that 5-HT (1-10 μM) also stimulates PGI2 production by a preparation of contractile smooth muscle cells : explants from bovine aortic media cultured for short periods. This effect is independent from 5-HT2 receptors : it is only partially inhibited (±30%) by ketan-serin (a selective and potent 5-HT2 antagonist) and is perfectly mimicked by a 5-HT1 agonist, 5-carboxamidotryptamine. 5-HT2 receptors seem to be linked to a phospholipase C (3), with subsequent accumulation of inositol tr isphosphate , Ins(1,4,5)P3, and diacylglycerol, an activator of protein kinase C. We have observed a stimulatory effect of phorbol 12-myristate, 13-acetate (a selective activator of kinase C) on PGI2 production by the bovine aortic smooth muscle cells (synthetic state), whereas it was totally ineffective on media explants preparation (contractile state). Furthermore, in the smooth muscle cells in culture, the 5-HT effect can be inhibited by (ethyl-isopropyl)amiloride, a potent and selective inhibitor of the Na+/H+ antiporter. In conclusion it appears that the regulation mechanisms of PGI2 production in arterial smooth muscle cells are strongly dependent an the phenotypic state of these cells. The control of PGI2 release via 5-HT2 receptors seems to involve a cytoplasmic alkalinization, via the activation of protein kinase C. The mechanism of 5-HT action in the media explants remains to be elucidated.(1) Coughlin, S.R. et al.: Proc . Natl. Acad. Sci. USA 78(11), 7134-7138, 1981.(2) Chamley-Campbell, J.H. and Campbell, G.K.: Atherosclerosis 40, 347-357, 1981.(3) Roth, B.L. et al.: J. Pharm. Exp. Ther. 238(2), 480-485, 1986.
