Iron-catalyzed trifluoromethylation with concomitant C–C bond formation via 1,2-migration of an aryl group

Abstract

Iron-catalyzed trifluoromethylation with concomitant 1,2-migration of an aryl group starting from diaryl allyl alcohol was achieved under mild conditions. This reaction system affords α-substituted-β-trifluoromethyl carbonyl compounds in high efficiency. In the case of substrates bearing different aryl groups, selective migration was observed.
