Abstract: Disulfide has been reduced by cerium trichloride and samarium in tetrahydrofuran to produce samarium thiolates. The “living” species reacts smoothly with <img src='/image/spc_char/alpha.gif' border=0> ,<img src='/image/spc_char/beta.gif' border=0>-unsaturated esters(nitriles) to afford <img src='/image/spc_char/beta.gif' border=0>-thioesters(nitrile) under mild and neutral conditions. The new thiolate anion also reacts with acyl halides, anhydrides and alkyl or benzyl halides to give thioesters and sulfides, respectively.
