Abstract

A Co(III)-catalyzed counter anion triggered desilylative direct ortho-vinylation of secondary benzamides is reported. The reaction furnishes the alkenylated product, exclusively, and no formation of the possible cyclic products was observed. Mechanistic studies suggest that the counter anion, SbF6](-), plays a crucial role in the desilylation. The utility of alkynylsilanes instead of terminal alkynes turned out to be a potential and practical approach to obtain the corresponding vinylated products. The developed methodology is compatible with a variety of functional groups.
