Partial metal-boron bond cleavage and coupling of a borylene with two CO ligands was observed upon reduction of a new bulky arylborylene complex. Both the borylene precursor and dianionic product were structurally and spectroscopically characterized. In contrast, reduction of an aminoborylene complex led to complete loss of the borylene ligand and classical Hieber reduction. A rationale for these differences based on DFT methods is presented.
新的大位阻芳基硼烯配合物还原时观察到部分金属-硼键断裂和双 CO 配体的硼烯偶联。硼烯前体和二阴离子产物均进行了结构和光谱表征。相比之下，氨基硼烯配合物的还原导致硼烯配体完全消失，并发生经典的 Hieber 还原。基于密度泛函理论（DFT）方法提出了这些差异的原理。
