The tricyclohexylphosphane adduct of cyclopalladated ferrocenylimine I exhibited high catalytic activity in the one-potborylation/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。

In one aspect, cobalt complexes are described herein. In some embodiments, such cobalt complexes employ bis(phosphine) or bis(imine) ligand and are operable as catalysts for borylation of arenes and aromatic heterocycles.
The cyclopalladated ferrocenylimine I and its phosphine adducts IIa–f were prepared and evaluated in the borylation of aryl halides. The tricyclohexylphosphine adduct IIb exhibited highly catalytic activity for the coupling of aryl and heteroaryl bromides containing various functional groups with low catalyst loading (2 mol%). Aryl and heteroaryl chlorides were smoothly converted into the corresponding
