Résumé :
By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has been established as a result of the carried out investigations that the introduction of the synthesized compounds into PVC composition improves the physical-mechanical properties, which has been connected with the availability of sulfur atoms, carbonyl groups and ether bond in the molecules of bis-adducts. The high operational indices from PVCplastics indicate good plasticizing properties of the synthesized bis-adducts, and therefore they can be recommended for practical use.

A series of 1:1 adducts of bis(morpholinedithiocarbamato) complex of VO(IV), 1:1 and 1:2 adducts of bis(morpholinedithiocarbamato) complexes of Ni(II) and Cu(II) with piperidine and morpholine have been synthesized and characterized by elemental analysis, molar conductance, magnetic susceptibility, IR, UV-Vis, and TGA/DTA techniques. Analytical data reveals that VO(IV) complex forms only 1:1 adducts with the formula [VO(morphdtc)2L].H2O while Ni(II) and Cu(II) complexes form both 1:1 and 1:2 adducts with 1:1 adducts having general formula Ni(morphdtc)2.L and Cu(morphdtc)2.L and 1:2 adducts having general formula Ni(morphdtc)2.L2and Cu(morphdtc)2.L2(morphdtc = morpholinedithiocarbamate, L = morpholine and piperidine). Antifungal activity of some complexes has been carried out against the fungal strainFusarium oxysporium. Thermal studies indicate a continuous weight loss. A square pyramidal geometry has been proposed for the 1:1 adducts of Ni(II) and Cu(II) complexes while an octahedral geometry has been proposed for the 1:1 adducts of VO(IV) and for the 1:2 adducts of Ni(II) and Cu(II) complexes.

Résumé :
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, and some are potent carcinogens in rodents. Carcinogenic PAHs are activated in the cells to metabolites that react with DNA to form covalent adducts. For most PAHs the reactive, electrophilic species which bind to DNA, are bay-region diol-epoxides. Application of 32P-postlabeling to PAH-DNA adducts analysis revealed that for some PAHs the adduct profiles generated in model systems are more complex and include adducts which are more polar than those formed by classic bay-region diol-epoxides. This minireview summaries the information gained on typical representatives of polar PAH-DNA adducts. Formation of triol-epoxide-DNA adducts was proposed for chrysene and a non-alterant PAH, benzo[b]fluoranthene (B[b]F). 5-OH-B[b]F, the precursor of B[b]F triol-epoxide, was found to be a potent tumor initiator in mouse skin. For planar PAHs such as dibenzanthracenes the possibility of bis-diol epoxide-DNA adducts formation was suggested. The most comprehensive data were obtained for dibenz[a,j]anthracene (DB[a,j]A). This hydrocarbon when applied to SENCAR mouse skin forms up to 23 species of adducts, most of which are polar. Among these polar adducts seven were identified as derived from DB[aj]A-3,4-10,11-bis-diol. Analysis of tumor-initiating activity showed, however, that this proximate metabolite was inactive in this respect. In contrast, an excellent correlation was observed between levels of less polar DNA adducts (i.e. those derived from bay-region diolepoxides) and skin tumor initiating activity of DB[a,j]A. Thus, while triol-epoxides seems to be involved in tumor initiating activity of the parent compound, non alterant B[b]F, the significance of bis-diol epoxide-DNA adducts, at least those derived from DB[aj]A, is minor.

Monomeric five coordinated adducts of bis(O-ethyldithiocarbonato)copper(II) of general formula [Cu(C2H5OCS2)2(L)], [L = 2-, 3-, 4-methylpyridines and 2-, 3-, 4-ethylpyridines] have been synthesized and characterized by elemental analysis, i.r. and electronic spectroscopy, magnetic and conductivity measurements. Analytical results show that the adducts have 1 : 1 stoichiometry. The adducts were found to be paramagnetic and their magnetic moments at room temperature lie within the 1.81–1.94 B.M. range and this indicates the presence of one unpaired electron. All the adducts have distorted square pyramidal geometry.

Résumé :
2012/2013
Fullerene C60 is a charming molecule, its beautiful symmetry and its unique properties are still intriguing scientific community after almost three decades from its discovery. Investigation of its properties and applications is still an active field. In our group we are interested especially in the biological aspect of fullerene sciences. In this field, polyfunctional derivatives are particularly attractive, for the increased solubility and for the possibility to attach different biologically active molecules on the same carbon cage. In the first project we studied different methods to control the site selectivity of the double 1,3-dipolar cycloaddition of azomethine ylides. To this purpose, we synthesized several bis-reactive templates with very different design, and we could obtain unusual fullerene-macrocyclic and fullerene-cyclophanes structures. A good degree of control of the site selectivity was achieved in some cases. A supramolecular approach to the control of the second cycloaddition was also developed. In the second part we focused our efforts in finding a feasible and scalable method to produce bis- or poly-functional fullerene derivatives from the easily accessible monoadduct. Triazine chemistry in combination with oxyethylenic chains allowed us to easily synthesize a library of polyfunctional, versatile and highly soluble derivatives. Some toxicological results indicate that this kind of compounds can be very useful carriers for drug delivery and some application in this sense are currently under investigation. Finally in a third part of the work we synthesized several fullerene-bipyridyl ligands and their ruthenium complexes. In this way we want to combine in the same molecule both the antiproliferative properties of ruthenium complexes and the photosensitizing effect of fullerene in order to obtain a synergistic effect against tumor cells.

Résumé :
La présente thèse décrit la synthèse de briques de base de fullerènes pour la préparation de dispositifs moléculaires photoactifs combinant C60 et porphyrines. La cycloaddition alcyne-azoture catalysée au cuivre (I) a été utilisée comme outil de synthèse pour la préparation des dérivés C60 complexes.L’utilité synthétique de synthons C60 a été montrée avec la préparation d’édifices moléculaires complexes présentant des propriétés spécifiques pour diverses applications. Ainsi, un système photoactif flexible combinant C60 et porphyrine a été synthétisé. Cependant la flexibilité de l’espaceur liant les sous-unités de ce composé conduit à des variations de structurales importantes et complique ainsi l’analyse des études photophysiques.Dans ce contexte, nous nous sommes proposé dans une première partie de la présente thèse de parfaitement contrôler l’orientation et la distance des différentes sous-unités au sein de systèmes C60-donneurs. Afin de répondre à ce besoin, nous avons construit une brique de base de C60 rigide ayant un groupe azoture aromatique. Ainsi, la réaction « click » avec un phénylacétylène conjugué au groupement donneur conduit à un espaceur rigide entre les deux sous-unités.La deuxième partie de ce travail a été consacrée à la synthèse d’hexa-adduits du C60 portant différents groupements fonctionnels. Une méthode de synthèse permettant de préparer des hexa-adduits du C60 fonctionnalisés a été mise au point au laboratoire.Cette stratégie a été modifiée et des composés de C60 comportant dix fonctions azotures et une fonction alcyne protégée ont été synthétisés; dans ce cas il est possible d’introduire dans un premier temps par une réaction click dix groupes fonctionnels. Et dans un second temps; après déprotection de la fonction alcyne, une seconde réaction de click permet alors de greffer un fonctionnel différent
The present PhD thesis manuscript is focused on the use of fullerene building blocks for the preparation of photoactive molecular devices combining C60 and porphyrins. Cu(I) Catalyzed alkyne-azide cycloaddition was used as a synthetic tool for the preparation of complex C60 derivatives. Specifically, in the first part (Chapter II-B), a flexible fullerene-porphyrin triad has been developed and the photophysical studies were performed. The flexible linker between the fullerene core and the azide groups prevented any conformational control on the relative orientation and distance between the two photoactive subunits connected together. This prompted the development of an analogous building block in which the azide unit is directly connected to the bridging phenyl ring (Chapter II-C). In this way, the click reaction with porphyrin-alkyne derivatives give access to hybrid systems with a controlled relative orientation of the two moieties. This is of fundamental importance for a better understanding of the structural parameters affecting the electron and/or energy transfer kinetic in such dyads.In the second part (Chapter III), a fullerene hexaadduct scaffold is used to build up sophisticated multiporphyrin systems for various applications. The preparation of these multi-chromophoric ensembles relies on the click-click approach developed in our group

The bonding of bis-adducts between electron donors (D), such as NH3 and PH3, with phosphinidenes RP: (R = H, CH3, NH2, PH2, PF2) was examined using density functional theory calculations. The structures were optimized at the B3LYP/6-311++G** level of theory. The main interest of this work is to find the trend in structural symmetry of the D—PR—D system. Accordingly, the magnitude of bond strength correlates well with the difference in ionization potential (IP) of the orbitals involved in the D—P interaction. In addition, we found the magnitude of the first bonding energy between D and PR is decisive for the symmetry of the D—PR—D system.

Fullerene derivatives have been widely used as electron acceptor for fabricating efficient polymer solar cells due to their high electron affinity and good electron mobility. It has been demonstrated that the molecular levels, chemical compatibility to conjugated polymer and solubility in processing solvent are key parameters in affecting the cell efficiency. In this study, a series of mono- and bis-adducts of C60 with similar structure, including ethyl (4-methylbenzyl)1,2-methano[60]fullerene- 61,61-dicarboxylate (MBEMDC), ethyl (4-ethylbenzyl)1,2-methano[60]fullerene- 61,61-dicarboxylate(EBEMDC), ethyl (4-isopropylbenzyl) 1,2-methano[60]fullerene- 61,61-dicarboxylate (iPBEMDC), ethyl (4-tert-butylbenzyl) 1,2-methano[60] fullerene-61,61-dicarboxylate (tBBEMDC), (4-n-butylbenzyl) 1,2-methano[60] fullerene-61,61-dicarboxylate(nBBEMDC), bis-ethyl (4-ethylbenzyl)1,2-methano[60] fullerene-61,61-dicarboxylate (bis-EBEMDC), bis-ethyl (4-isopropylbenzyl) 1,2-methano[60]fullerene-61,61-dicarboxylate (bis-iPBEMDC), bis-ethyl (4-tert- butyl-benzyl)1,2-methano[60] fullerene-61,61-dicarboxylate(bis-tBBEMDC), benzyl- n-hexyl 1,2-methano[60]fullerene-61,61-dicarboxylate benzyl fulleropyrrolidine (BHMDCmix) and ethyl (4-tert-butylbenzyl) 1,2-methano[60]fullerene-61,61- dicarboxylate benzyl fulleropyrrolidine (tBBEMDCmix), were designed and synthesized via Bingel-Hirsch reaction and/or Prato reaction. The obtained products were characterized using NMR, MALDI-TOF and EA. Moreover, cyclic voltammetry (CV) and UV-vis were employed to investigate the energy levels and optical properties of these new molecules.

Résumé :
The olefin metathesis reaction has become one of the most powerful carbon-carbon bond forming reaction in synthetic chemistry. This work has expanded the utility of olefin metathesis in metal coordination spheres in three major directions (1) the synthesis and characterization of trans-spanning bis(pyridine)PtCl2 complexes, (2) the developme-adducts of polyacetylene (PA), and (3) the development of regioregular -adducts of poly(phenylene-vinylene) (PPV). Chapter I gives a brief overview of olefin metathesis and previous applications to organometallic substrates. Chapter II details the synthesis of pyridine ligands containing alkenyl substituents, 2-NC5H4(CH2O(CH2)nCH=CH2) (n = 1, 2), 3-NC5H4(CH2O(CH2)nCH=CH2) (n = 1-5, 8, 9), and 3,5-NC5H3(p-C6H4O(CH2)7CH=CH2)2. Metalation of the new ligands with PtCl2 affords the corresponding trans-bis(pyridine)dichloroplatinum complexes, trans-PtCl2(2-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 1, 2), trans-PtCl2(3-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 1-5, 8, 9), and trans-PtCl2(3,5-NC5H3(p-C6H4O(CH2)7CH=CH2))2. Ring-closing metathesefirst generation catalyst followed by hydrogenations with Pd/C afford the title complexes trans-PtCl2-(NC5H4(CH2O(CH2)2n+2OCH2)H4C5N)] (n = 1, 2), trans-PtCl2-(NC5H4(CH2O(CH2)2n+2OCH2)H4C5N)] (n = 4, 8, 9), and trans-PtCl2-(NC5H3(p-C6H4O(CH2)12O-p-C6H4)2H3C5N)]. Reactions with methylmagnesium bromide afford trans-PtCl(CH3)(3-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 2, 8) and trans-PtCl(CH3-(NC5H4(CH2O(CH2)nOCH2)H4C5N)] (n = 10, 18), which feature dipolar rotators. Low temperature NMR spectra in the latter remained facile on the NMR time scale in CDFCl2 at -120 degrees Celsius. Chapter III focuses on the application of ROMP with organometallic monomers to form metal pi-adducts of polyacetylene. The new complex (n4-benzene)Cp*Ir has been synthesized, crystallographically characterized, and evaluated in the ROMP reaction. Monomers (n4-benzene)CpIr, [(n6-COT)CpRu][PF6], and (n4-COT)Fe(CO)3 were also evaluated in the ROMP reaction. ROMP of (?4-benzene)CpIr with Grubbs' first generation catalyst afforded the conductive regioregular polymer CpIr-PA. Chapter IV focuses on the synthesis of the divinyl benzene complexes [Cp*Ir(C6H4(CH=CH2)2)][BF4]2 and [Cp*Ru(C6H4(CH=CH2)2)][OTf] and their polymerization via ADMET to afford PPV systems. Treatment of divinyl benzene ed the conductive regioregular polymers [Cp*Ir-PPV][BF4]2n and [Cp*Ru-PPV][OTf]n. The photophysical properties of the new -metal adducts of PPV exhibit blue-shifts relative to typical PPVs and retain strong UV absorption.

The second part of the present work provides an insight into the chemistry of cyclic (alkyl)(amino) carbene-stabilized nickel complexes as well as it encloses some more detailed studies on the properties and reactivity of the free carbenes itself. The results presented herein can be divided into four sections: I. synthesis and characterization of cyclic (alkyl)(amino) carbene-stabilized nickel carbonyl complexes, II. which allow the evaluation and quantification of the steric and electronic properties of these cyclic (alkyl)(amino) carbenes, III. first studies on the reactivity of these novel nickel complexes, and IV. investigations on C–F and C–H bond activation at the carbene center of cyclic (alkyl)(amino) carbenes
