摘要

报告了一种与 Py2BH（Py = 吡啶）型硼基供体配体的铑 PBP 型钳状配合物及其去质子化过程，该过程在形成新的 C-C 键的同时产生了硼烷基配合物。机理研究表明，两个去质子化的物种之间存在同分异构现象，从而产生了配体稳定的硼化物和配体稳定的硼烯基团。

Evidence for a boride–borylene-ligand-tautomerism leading to a remote C–C-bond and concomitant boryl ligand formation

A rhodium PBP-type pincer complex with boron-based donor ligand of the type Py2BH (Py = pyridine) and its deprotonation is reported, which led to a boryl complex under concomitant formation of a new C—C-bond. Mechanistic investigations indicate the presence of a tautomerism between two deprotonated species, giving rise to a ligand-stabilized boride and a ligand-stabilized borylene motif.
