A facile and efficient method for the α‐trifluoromethylation of carbonyl compounds and enolsilanes has been accomplished through application of a photoredox catalysis strategy. A one‐flask procedure for the direct α‐trifluoromethylation and α‐perfluoroalkylation of ketone, amide, and ester substrates as well as silylketene acetals is described (see scheme).
