Abstract

Abstract A variety of epoxides underwent facile cleavage by thiols under the catalysis of 1- methyl-3-butylimidazolium bromide,[bmIm] Br, to produce the corresponding β-hydroxy sulfides with high regio-and stereo-selectivity. On the other hand, a specially designed basic ionic liquid,[bmIm] OH, efficiently catalyzes the thiolysis of α, β-epoxy ketones providing β- keto sulfides through simultaneous retro-aldol cleavages. The reactions are clean, high ...
