A visible‐light‐induced radical difluoromethylation of alkynoates using [bis(difluoroacetoxy)iodo]benzene as the CF2H radical precursor was developed for the first time. 3‐Difluoromethyl‐substituted coumarins were synthesized via a radical difluoromethylation/cyclization/ester migration cascade. The mild and catalyst‐free conditions, as well as the good functional group tolerance, render this protocol an alternative and green strategy for the synthesis of 3‐difluoromethyl‐substituted coumarins.
Radical change: A visible‐light‐induced radical difluoromethylation of alkynoates by [bis(difluoroacetoxy)iodo]benzene to yield 3‐difluoromethylated coumarins was developed. The method is an alternative green synthesis with good functional group tolerance.
