A new route for a one-pot synthesis of methyl sulfoxides from thiophenols/thiols and dimethyl sulfoxide using an electrochemical technique was developed. This protocol proceeded smoothly by employing electrons and hydrogen peroxide as clean oxidants, and a wide range of aromatic and aliphatic sulfoxides were synthesized in moderate to good yields.
oxidation of prochiral sulfides to sulfoxides by hydrogen peroxide in aqueous solutions. The alloxazinium unit was appended to the primary face of α- and β-cyclodextrins via a linker with variable length. A series of sulfides was used as substrates: n-alkyl methyl sulfides (n-alkyl = hexyl, octyl, decyl, dodecyl), cyclohexyl methyl sulfide, tert-butylmethyl sulfide, benzylmethyl sulfide and thioanisol. α-Cyclodextrin

and rat liveralcoholdehydrogenases with respect to ethanol as substrate. These compounds also were uncompetitive inhibitors in vivo, which is advantageous since the inhibition is not overcome at higher concentrations of ethanol, as it is with competitive inhibitors, such as pyrazole.

An increasing number of reactions of sulfenic acidanions are being demonstrated in the literature. As such, mild, general and reliable means for the generation of sulfenates are due. In the current paper, an addition/elimination of 2-sulfinyl acrylates using various nucleophiles is demonstrated and evaluated as a protocol for alkane- and arenesulfenate generation. Cyclohexanethiolate, methoxide and
