Cp∗Co(III)-catalyzed oxidative C–H alkenylation of benzamides with ethyl acrylate

Abstract

The utility of Cp∗Co(III)-catalysts was expanded to oxidative C–C bond-forming reaction. In situ-generated Cp∗Co(III)-catalyst, rather than a preformed cationic Cp∗Co(III)-complex, was effective. Oxidative alkenylation of benzamides and acetanilide with ethyl acrylate proceeded with silver acetate as a stoichiometric oxidant, giving products in up to 93% yield.
