Cyclic complex 2 with bridging carbonylligands was synthesized from a facile and reversible intermolecular carbonyl–borylene ligandcoupling reaction at room temperature. Complex 2 exhibits an unprecedented coordination mode for boron–metal complexes, which is also reflected in its remarkable 11B NMR chemical shift of −57.2 ppm. Findings from spectroscopic, X‐ray, and computational studies are presented
在室温下,通过容易且可逆的分子间羰基-硼烯配体偶联反应,合成了具有桥接羰基配体的环状配合物2。配合物2对硼-金属配合物表现出前所未有的配位模式,这也反映在其显着的11 B NMR化学位移-57.2 ppm上。提出了从光谱学,X射线和计算研究中得到的发现,以及提出的机制。
