Visible-light Induced Radical Aryldifluoromethylation of N-Arylacrylamides by [bis(difluoroacetoxy)iodo]benzene

Abstract Visible light-induced radical aryldifluoromethylation of N-arylacrylamides using [bis(difluoroacetoxy)iodo]benzene as a difluoromethylation reagent is reported for the first time. The inexpensive and readily accessible reagents and the mild reaction conditions render this method an alternative and practical strategy for the synthesis of difluoromethyl substituted oxindoles.
