Efficient Synthesis of β-Alkyl/Arylsulfanyl Carbonyl Compounds by In-TMSCl-Promoted Cleavage of Dialkyl/Diaryl Disulfides and Subsequent Michael Addition.

A convenient and efficient procedure for the synthesis of β-alkyl/arylsulfanyl carbonyl compounds has been developed by a simple one-pot reaction of dialkyl/diaryl sulfides with α,β-unsaturated aldehydes, ketones, carboxylic esters, and nitriles in presence of indium and trimethylsilyl chloride under sonication.
