The installation of trifluoromethylgroups has become an essential step across a number of industries such as agrochemicals, drug discovery, and materials. Consequently, the rapid introduction of this critical functional group in a predictable fashion would benefit current practitioners in those fields. This communication describes a mild trifluoromethylation of benzylic C-H bonds with high selectivity

Herein, we describe an iron-catalyzed benzylic C–H borylation reaction. The reaction targets primary and secondary C(sp3)–H bonds to deliver high-value boronic esters under mild conditions with short (7–8 min) reaction times. Functional groups are well tolerated, and complete site selectivity is observed in the presence of multiple benzylic C–H bonds.
