A novel protocol for ortho-C–H alkylation of aromatic and heteroaromatic ketones and esters under Cp*Co­(III) catalysis has been developed for the first time. The reaction proceeds through initial cyclometalation via weak chelation-assisted C–H bond activation, followed by coordination of activated alkene, insertion between Co–C, and protodemetalation.
