Cobalt-catalyzed ortho-alkenylation of aromatic aldimines via chelation-assisted C–H bond activation

An ortho-alkenylation reaction of an aromatic aldimine with an internal alkyne is efficiently promoted by a cobalt catalyst generated from CoBr2, triarylphosphine, and iPrMgBr. The reaction takes place under mild room-temperature conditions to afford, upon acidic hydrolysis, a variety of ortho-alken...
