Photoredox Catalysis: A Mild, Operationally Simple Approach to the Synthesis of α‐Trifluoromethyl Carbonyl Compounds

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).
