Use of tert-Butyl Sulfoxides as Latent Sulfenyl Cation Equivalents

Brichard, M.H.,Musick M.,Janousek, Z.,Viehe, H.G.

, p. 2379 - 2386 (2007/10/02)

This paper reports a new and practical method of trifluoroacetoxysulfenylation of olefins, starting from t-butyl sulfoxides.The latter, in a mixture of trifluoroacetic anhydride and trifluoroacetic acid, do not undergo the Pummerer reaction.Instead, sulfenyltrifluoroacetates 2 are formed and they add in situ to olefins.
