Reactions of hexamethyldisilathiane (HMDST) with carbonyl compounds under the catalytic activity of CoCl2 center dot 6H(2)O or trimethylsilyltriflate lead to a simple and general access to thioaldehydes and thioketones, which could be isolated as their cycloadducts with dienes. The use of CF3SO3SiMe3 in reactions with cyclohexadiene allows a stereopredetermined access to either the endo- or the exo-isomer. Furthermore, on using P-silyl-substituted acetylenic ketones, a smooth access to acetylenic thioketones can be achieved. In reactions with aromatic and heteroaromatic o-azido aldehydes, the reactivity of HMDST may be finely tuned toward the synthesis of o-azido thioaldehydes, fused isothiazole ring systems, aromatic and heteroaromatic o-amino aldehydes, and o-amino thioaldehydes. HMDST proved also very efficient in thionating more intriguing substrates such as acylsilanes. Thus, thioacylsilanes, thioformylsilanes, unsaturated thioacylsilanes and -stannanes can be obtained in good yields. Ethylenic thioacylsilanes showed an interesting behavior leading to a general synthesis of functionalized dithiins. Finally, HMDST led also to the synthesis of bis(thioacylsilanes), which led to the formation of new silylated thiaheterocyclic systems.

pMATM2-b-p(MMA-co-BMA) diblock copolymers composed of a block of poly[bis(trimethylsiloxy)methylsilyl methacrylate] (MATM2) and a second block of a random copolymer of methyl methacrylate (MMA) and n-butyl methacrylate (BMA) were synthesized by the reversible additionfragmentation transfer process with controlled molar masses and low molar mass dispersities. Paints were formulated using these diblock copolymers as binders, without any biocides, or associated with low amounts of biocidal compounds such as dicopper oxide (Cu2O), 4,5-dichloro-2-n-octyl-4-isothiazole-3-one (DCOIT), and 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1H-pyrrole-3-carbonitrile. All the coatings exhibited a hydrophobic surface at the initial stage with an evolving surface chemistry when immersed in artificial seawater. The erosion of the coatings was shown to be driven by the molar proportion of MATM2 units in the diblock copolymer. The antifouling properties were evaluated by in situ static immersion in the Mediterranean Sea. Cu2O (20 wt %)-DCOIT (2 wt %)-based coatings with 30 mol % of MATM2 in the seawater-hydrolyzable binder exhibited similar antifouling performances to a commercially available self-polishing coating over 16 months of field immersion. Contact angles and mass loss measurements, as well as scanning electron microscopy observations enabled the investigation of the parameters influencing the antifouling activity of the coatings.

1,2-Dithiolopyrrolones and their heterologues of type 1 are resonance stabilized systems displaying a high dipole moment. Upon oxidation with organic peracids compounds 2, 5, 15a, 16a, 20a and 25a gave the corresponding S(2)-oxides and, depending on substituents, in some cases the S(2)- and S(1)-dioxides. The S(2)-monoxides showed a proclivity to disproportionation and were easily reduced to dithioles with symmetrical dimethylhydrazine. From S(2)-oxides and several primary amines bicyclic isothiazole-S-oxides were obtained (S/N-exchange reaction). From the N-unsubstituted isothiazole S-oxide 10e the N-hydroxyisothiazole 9d was synthesized by an aza-Pummerer-type rearrangement. The assumption is made that S(2)-oxides may be biologically important as active metabolites of pyrrothines and analogues of type 1 in their action as antibacterials and antimycobacterials.

HETEROCYCLIC ANIONS OF ASTROBIOLOGICAL INTEREST

As more complex organic molecules are detected in the interstellar medium, the importance of heterocyclic molecules to astrobiology and the origin of life has become evident. 2-Aminothiazole and 2-aminooxazole have recently been suggested as important nucleotide precursors, highlighting azoles as potential prebiotic molecules. This study explores the gas-phase chemistry of three deprotonated azoles: oxazole, thiazole, and isothiazole. For the first time, their gas-phase acidities are experimentally determined with bracketing and H/D exchange techniques, and their reactivity is characterized with several detected interstellar neutral molecules (N2O, O-2, CO, OCS, CO2, and SO2) and other reactive species (CS2, CH3Cl, (CH3)(3)CCl, and (CH3)(3)CBr). Rate constants and branching fractions for these reactions are experimentally measured using a modified commercial ion trap mass spectrometer whose kinetic data are in good accord with those of a flowing afterglow apparatus reported here. Last, we have examined the fragmentation patterns of these deprotonated azoles to elucidate their destruction mechanisms in high-energy environments. All experimental data are supported and complemented by electronic structure calculations at the B3LYP/6-311++G(d,p) and MP2(full)/aug-cc-pVDZ levels of theory.
