Role of Cu(OTf)2 and lutidine. See the SI for more details. (a) Reaction efficacy dependency on lutidine using Cu(OTf)2 or electricity as the oxidant. (b, c) Cyclic voltammograms. Cu(OTf)2 (5 mM), Pd(OAc)2 (5 mM), lutidine (5 or 10 mM), and 0.1 M nBu4NBF4 in HFIP/AcOH (1:2), 100 mV s–1, room temperature.
