Desilylation of (Z)-α-dimethylphenylsilyl vinyl sulfides with fluoride ion:1 revised mechanism for phenyl group migration in substrates containing an electron-withdrawing group β to the sulfur
Abstract
A detailed investigation of the desilylation of (Z)-α-dimethylphenylsilyl vinyl sulfides with fluoride ion has shown that in substrates containing an electron-withdrawing group β to the sulfur, phenyl group migration occurs as a result of a fluoride ion catalyzed retro-Michael reaction.
