Trialkylsulfonium dicyanamides show surprisingly low viscosities down to -20 degrees C and are therefore highly interesting liquid materials for separation processes and electrolyte applications at low temperatures.

Cytochromes of the c-type contain hemes covalently attached via one or, more generally, two thioether bonds between the vinyls of heme b and the thiols of cysteine residues of apocytochromes. This post-translational modification relies on membrane-associated specific biogenesis proteins, referred to as cytochrome c maturation systems. At least three different versions (i.e. Systems I-III) are f...

Nanocomposite polymers are prepared using a new sustainable materials synthesis process in which d-Limonene functions simultaneously both as a solvent for recycling polystyrene (PS) waste and as a monomer that undergoes UV-catalyzed thiol-ene polymerization reactions with polythiol comonomers to afford polymeric products composed of precipitated PS phases dispersed throughout elastomeric poly(t...

Cytochromes c are hemoproteins, with the prosthetic group covalently linked to the apoprotein, which function as electron carriers. A class of cytochromes c is defined by a CXXCH heme-binding motif where the cysteines form thioether bonds with the vinyl groups of heme. Plastids are known to contain up to three cytochromes c. The membrane-bound cytochrome f and soluble cytochrome c6 operate in p...

In vitro formation of Hydrogenobacter thermophilus cytochrome c552 has previously been demonstrated (Daltrop, O., Allen, J. W. A., Willis, A. C., and Ferguson, S. J. (2002) Proc. Natl. Acad. Sci. U. S. A. 99, 7872-7876). Now we report that the single cysteine variants of H. thermophilus c552, which bind heme via a single thioether bond, also form in vitro. Furthermore, reaction of the apocytoch...

zn/acoh on silica gel converts a range of structurally different sulfoxides to their corresponding thioethers in excellent yields under microwave irradiation. it has been found that chemoselective deoxygenation of sufoxides can be achieved in the presence of other reducible functional groups such as acetals, acids, amides,   esters, ketones and nitriles.

Mutacin II is a post-translationally modified lantibiotic peptide secreted by Streptococcus mutans T8, which inhibits the energy metabolism of sensitive cells. The deduced amino acid sequence of promutacin II is NRWWQGVVPTVSYECRMNSWQHVFTCC, which is capable of forming three thioether bridges. It was not obvious, however, how the three thioether bridges are organized. To examine the bridging, th...

Thioether-phosphite ligands (SP’s) with axially chiral (S)-H0- or (S)-H8-binaphthyl moiety and their [Rh(COD)(SP)]BF4 complexes have been synthesized to study coordination chemistry catalytic features compare them those of the structurally analogous phosphine-phosphites (PP’s). NMR exchange studies on showed selective 1,5-cyclooctadiene dynamics. Firm evidence has found that this fluxional proc...
