Desilylative Pummerer-like rearrangement of α-trimethylsilyl-substituted sulphoxides and sulphides: formation of α-acyloxy and α-halogeno sulphides
Abstract
α-Trimethylsilyl-substituted sulphoxides and sulphides undergo rearrangement with loss of the silyl group when treated respectively with trifluoroacetic anhydride and with N-halogenosuccinimide in the presence of trifluoroacetic acid, giving α-acyloxy sulphides and α-halogeno sulphides.
