6‐Trifluoromethyl‐Phenanthridines through Radical Trifluoromethylation of Isonitriles

Abstract

A radical approach toward 6-perfluoroalkylphenanthridines employs the Togni reagent or derivatives thereof as radical precursors and occurs in the absence of a transition metal. Bu4NI is applied as radical initiator and phenanthridines are formed in good to excellent yields. In contrast to the currently intensively investigated trifluoromethylation of arenes, the arene core is formed during the trifluoromethylation in this approach.
