The tricyclohexylphosphane adduct of cyclopalladated ferrocenylimine I exhibited high catalytic activity in the one-pot borylation/Suzuki-Miyaura coupling (BSC) reaction with low catalyst loading (2 mol-%). Various biaryls were obtained in good to excellent yields for 37 examples. This process was applied to aryl and heteroaryl halides (Br and Cl) containing a variety of functional groups and did not
环钯二茂铁亚胺 I 的三环己基膦加合物在低催化剂负载量(2 mol%)的一锅硼化/铃木-宫浦偶联(BSC)反应中表现出高催化活性。对于 37 个实施例,以良好到极好的收率获得了各种联芳基化合物。该方法适用于含有多种官能团的芳基和杂芳基卤化物(Br和Cl),不需要过量的磷烷配体,也不需要在第二步中加入钯催化剂。
