A new synthesis of vinyl sulphides by Lewis acid promoted reaction of [chloro-(arylthio)methyl]trimethylsilanes with trisubstituted alkenes
Abstract
Treatment of the α-chloro-α-silyl sulphides (1) or (5) with trisubstituted alkenes (6) in the presence of SnCl4 gave the vinyl sulphides (7) or (8), the formation of which involves a carbenium ion rearrangement controlled by the silyl group.
