The old one two: A sequential iridium‐catalyzedborylation and copper‐catalyzed trifluoromethylation of arenes is described (see scheme; Pin=pinacol). The reaction is conducted under mild reaction conditions and tolerates a variety of functional groups. The advantages of this tandem procedure are demonstrated by the late‐stage trifluoromethylation of a number of biologically active molecules.
