MATTERS ARISING NATURE CATALYSIS specifically, the addition of 5 mol% amine 1 with 65 ppm palladium means that approximately 9.3× 10− 4 mol% palladium was present in the reaction mixture. In other words, the catalytic turnover number was at least 108 000, which suggests that the trace palladium species was exceptionally reactive. Here, we compared palladium catalysis in the presence of amine 1, PCy3 and the combination of both, to find that PCy3 had an inhibitory effect, which is reminiscent of Ahlquist and Norrby 17. Without amine 1 or PCy3, we could lower the reaction temperature from 110 to 24 C to carry out a ligand-free Suzuki–Miyaura coupling. The role of amine 1 with more complex substrates may warrant further study.
