Abstract:
Chiral γ-ketothiols, thioacetates, thiobenzoate, disulfides, sulfones, thiosulfonates, and sulfonic acids were obtained from β-pinene for the first time. New compounds open up prospects for the synthesis of other polyfunctional compounds combining a biologically active pinane fragment with various pharmacophore groups. It was shown that the syntheses of sulfanyl and sulfonyl derivatives based on 2-norpinanone are characterized by high stereoselectivity in comparison with similar reactions of pinocarvone. The conditions for the preparation of diastereomerically pure thioacetyl and thiobenzoyl derivatives based on pinocarvone, as well as for the chemoselective oxidation of γ-ketothiols with chlorine dioxide to the corresponding thiolsulfonates and sulfonic acids, were selected. The effect of the VO(acac)2 catalyst on the increase in the yields of thiosulfonates was shown. A new direction of the transformation of thiosulfonates with the formation of sulfones was revealed. In the case of pinocarvone-based sulfones, the configuration is inversed at the C2 atom. An epimerization scheme is proposed.

Abstract:
Sulfonyl fluoride systems and their derivatives, RS02F, where R represents hydrocarbon/fluorocarbon moieties continue to be of considerable interest. The incorporation of the sulfonyl fluoride group (S02F) into molecular systems can lead to compounds that are useful as ion-exchange resins, surface active agents, fuel cell electrolytes, and strong sulfonic acids/salts. Interest in preparing SF5 containing sulfonyl fluorides led to the synthesis of the ᵝ-sultone, SF5CHCF20S02, and its rearranged product. Hydrolysis of the sultone gave SF5CH2S02F which led to the sulfonic acid and salt, SF5CH2S03H•H20 and (SF5CH2S03)2Ca. Esters of the sultone were prepared by reaction of the sultone with fluorinated alcohols in the presence of NaF to give SF5CH(S02F)C(O)OR where R = CH2CF3 and CH(CF3)2. Polymeric SF5/S02F containing esters were prepared by reaction of allyl esters, RCX(S02F)C(O)OCH2CH=CH2, in ultraviolet light where R = CF3 or SF5 and X= H or F. Fluorinated silver carboxylate salts have been useful in preparing fluoroesters from alkyl iodides. Therefore, a new silver salt, FS02CF2C(0)0Ag was prepared and characterized; its reaction with (CH3)3SiI, HOCH2CH2I and alkyl bromides and iodides are reported. In addition, new SF5 containing fluoropolymers were synthesized via reaction of fluorinated olefins with SF5Br. Reactions of SF5 containing olefins with CF30Cl, C1F and Cl2 provide reagents that may be of potential use as precursors to sulfonyl fluoride containing systems. All new compounds were characterized by their respective infrared, nmr and mass spectra.

Abstract:
Monomeric and polymeric fluoroalkyl sulfonyl fluorides, sulfonate salts and sulfonic acids have qualities desirable for use as electrolytes in alternative energy sources such as fuel cells and solid polymer electrolyte lithium batteries. Since the nature of the fluoroalkyl group affects the properties of these compounds, new monomeric and polymeric fluoroalkyl sulfonyl fluorides, sulfonate salts and sulfonic acids were prepared in this work. Simple compounds prepared in this work were: the fluoroalkyl sulfonyl fluorides, sulfonate salts and sulfonic acid CHF (OCF₂CF2SO₂ F)₂ CF₂(OCF₂CF₂SO₂F) ₂ CH₂(OCF₂CF₂SO3Na) ₂ CF₂(OCF₂CF₂SO3 ) ₂Ca , CF₂(OCF₂CF₂SO3H) ₂ prepared by means of electrochemical fluorination; FC (CF3 ) ₂OCH₂CH₂OCF₂CF₂SO₂F prepared using the adduct of hexafluoroacetone and silver fluoride; CH₃OCF₂CF₂SO₂F prepared as a substrate for free-radical substitution reactions of fluorinated species; and the pentafluorosulfur lithium sulfonate salts SFsCHFSO₃Li and SFsCF₂SO₃Li. Novel compounds containing both alcohol and fluoroalkyl sulfonyl functional groups were prepared: the chlorohydrin ClCH₂CH (OH) CH₂OCF₂CF₂SO₂F; the benzyl ethers HOCH₂CH (OCH₂C6Hs) CH₂OCF₂CF₂SO₂F and C6HsCH₂OCH₂CH (OH) CH₂OCF₂CF₂SO₂F as a product mixture; and the diol HOCH₂CH (OH) CH₂OCF₂CF₂SO₂F. The diol was found to be a useful synthon for the preparation of two polymeric fluoroalkyl sulfonyl fluorides: the polyester [C (O)CF₂CF₂CF₂ C (O) OCH₂CH (CH₂OCF₂) CF₂SO₂F] O]n by reaction with perfluoroglutaric anhydride and a polyurethane formed with 1,6-diisocyanohexane. Other polymeric compounds prepared were: the sulfonyl fluoride, sulfonate salt and sulfonic acid [OCH₂CH (CH₂OCF₂CF₂SO₂F)]n, [OCH₂CH (CH₂OCF₂CF₂SO₃Na)]n, and [OCH₂CH (CH₂OCF₂CF₂SO₃H)]n prepared by homopolymerization of the epoxide OCH₂CHCH₂OCF₂CF₂SO₂F; a cross-linked copolymer of the same epoxide; and the fluoroalkyl sulfonyl fluoride polyacrylat [-CH₂-CH-(CO₂CH₂CH₂CF₂CF₂OCF₂CF₂SO₂F)]n prepared from the acrylate ester H₂C=CHC (O) OCH₂CH₂CF₂SO₂F. ¹H, ¹⁹F and ¹³C nuclear magnetic resonance spectroscopy, infrared spectroscopy, mass spectrometry, melting point or boiling point, elemental analysis, contact angles, optical clarity, refractive index, and specific conductivity were among the techniques used to characterize the compounds.

Abstract:
Pentafluorosulfur (VI) bromide (SF5Br) adds to olefins of the form CX2=CX2, where X= H or F, with the pentafluorosulfur group usually adding to the carbon with more hydrogens attached to it. This series of compounds was used in an attempt to prepare the corresponding sulfonic acid hydrates of the general formula SF5CX2CX2SO3H·nH2O, in order to have these compounds tested as possible fuel cell electrolytes. The reaction scheme involved reflux of the SF5Br adduct with an equimolar amount of sodium sulfite in 50% ethanol for two days, followed by acidification of the recovered solid material using HCl or H2SO4.

Abstract:
Sulfur trioxide (SO₃) adds to fluoroolefins of the form RCF=CF₂, (where R = F, SF₅, CF₃, CF₃OCF₂, CF₂=CF(CF₂)₂, CF₃(CF₂)₃O, CF₃O(CF₂)₂OCF₂, or CH₂ClCHClCH₂), yielding the fluorinated [beta]-sultones, RCFCF₂OSO₂. In the case of CF₃(CF₂)₃OCF=CF₂, a reverse addition occurs, giving the sultone, CF₃(CF₂)₃CF₂2OCFCF₂SO₂O. The fluoro [beta]-sultones are capable of undergoing different reactions, such as rearrangement, hydrolysis, esterification, and polymerization. These reactions, will result in the formation of compounds containing the fluorosulfonyl grouping (SO₂F); it is this group that yields the corresponding sulfonic acid upon base/acid treatment. The addition of sodium bisulfite to CF₃CF= CF₂ and CF₃(CF₂)₄CF=CF₂ in the presence of (C₆H₅CO)₂O₂ and Na₂B₄O₇·10H₂O was also studied to produce the corresponding sulfonic acid hydrates of the general formula, R[subscript f]CFHCF₂SO₃H·nH₂O. These acids were prepared, and thus, tested as possible fuel cell electrolytes. Infrared, ¹H and ¹⁹F nuclear magnetic resonance and mass spectra, as well as elemental analyses, will be presented in order to support the proposed structures for the resulted compounds.

Abstract:
Part I describes the preparation of a number of useful intermediates from the sultone F5SCHCF2OSO2 (1). These intermediates include the following: the ketene F5SC(SO2)=C=O (21), the unique sultone F4S=CCF2OSO2 (23), and various ionic intermediates of the form Y+ [F5SC(SO2F) COX]-. These intermediates play an important role in providing new pathways for preparing fluorosulfonic acid precursors. Fluorosulfonic acids are excellent candidates to improve the efficiency of environmentally safe fuel cells. It was possible to obtain new derivatives of 1 by various reactions of 21, 23 and the ionic intermediates, but it was not possible to introduce an alkyl substituent with either of the intermediates. Part II is concerned with the synthesis of SF5 containing epoxides as possible monomers. When polymerized, materials of high dielectric strength and high chemical resistance should be obtained. The reaction chemistry of one of the epoxides was investigated and it was found that all reactions studied were accompanied by the loss of the SF5 group. Thus, it was not possible to obtain any polymeric materials. Part III deals with the synthetic accessibility of SF$\sb5$ malonic esters and thence of SF$\sb5$ acrylic esters. These compounds should serve as building blocks in the synthesis of SF$\sb5$ containing pyrimidines. The CF3 analogue, 5-trifluoromethyl uracil, is used as an antiviral drug. In order to synthesize either SF5 malonic ester or 2-SF5 acrylic ester an SF5 group has to be introduced at a secondary carbon. A secondary SF$\sb5$ compound could be synthesized (F5SCH (COOC2H5) (CHBrOAc)) but could not be converted to the respective malonic ester F5SCH (COOC2H5) compound. Part IV describes the reactions and preparations of Parts I-III.

Abstract:
We propose a planate conducting polymer actuator which can transform only its central part locally and a micro pump using its actuator as a drive source. We have developed a planate conducting polymer actuator based on polypyrrole and two types of acids, such as p-phenol sulfonic acid and dodecylbenzene sulfonic acid, by electrodeposition. Its structure was patterned bimorph structure with anion-driven, cation-driven and bimorph layers. The planate conducting polymer actuator could deform only its central part locally. And, we have proposed a micro pump using the planate conducting polymer actuator as the drive source. The water level in the flow channel of micro pump shows the reciprocating motion measuring ±2 mm in accordance with the oscillation of the bimorph conducting polymer actuator which was approximately 28 μl/min. The oscillating volume can be controlled by the application of electrochemical potential and its scan rate applied to the actuator.

Abstract:
CYP2B6 is a drug metabolizing cytochrome P450 (CYP) that has anti-obesity properties, but also increases non-alcoholic fatty liver disease (NAFLD) in hCYP2B6-transgenic mice compared to Cyp2b-null mice. hCYP2B6-transgenic mice are also more susceptible to perfluorooctane sulfonic acid (PFOS) toxicity, a lipid-like toxicant used in stains, varnishes and firefighting foams that increase NAFLD. Our recent research demonstrates that CYP2B6 metabolizes dietary polyunsaturated fatty acids into the oxylipins, 9-HODE and 9-HOTre, which are strong peroxisome proliferator activated receptor alpha (PPARa) agonists and weak PPARg agonists. The purpose of our studies is to better understand the mechanisms behind PFOS and oxylipin-mediated hepatic steatosis. To test whether PFOS, 9-HODE or 9-HOTrE alter mitochondrial metabolism, Seahorse Mitostress assays were performed using HepG2 cells treated with 0.2, 1 and 5mM PFOS, 9-HODE and 9-HOTrE for 24 hours (n=5). Both PFOS and 9-HOTrE increased spare respiratory capacity in a concentration-dependent manner with lesser effects by 9-HODE. qPCR was performed following exposure of HepG2 cells to 1 and 5 mM of each compound to investigate changes in gene expression that may explain alterations in mitochondrial respiration or hepatic steatosis. PFOS repressed expression of ANGPTL4, a biomarker of PPARgactivation. 9-HODE induced CD36 and FASN expression, genes involved in fatty acid uptake and synthesis. 9-HOTrE induced SREBF1 and Cpt1a expression, genes involved in sterol synthesis and fatty acid transport into the mitochondria and may partially explain the increase in SRC. Thus, based on current results, PFOS is associated with reduced transport of lipids from the liver and 9-HODE increases lipid uptake; both would increase steatosis through different mechanisms. 9-HOTre may increase metabolism and therefore reduce steatosis.
