Recent developments in main group chemistry towards the activation and conversion of N have lead to the revelation that boron can greatly affect these processes. Boron is capable of acting both as a borane Lewis acid to activate metal-N complexes and as an ambiphilic borylene able to activate free N. The latter example is capable of both accepting and donating electron density in a manner reminiscent of transition metal systems containing both filled and empty d-orbitals.
近年来,主族化学在 N 原子的活化和转化方面的进展表明,硼可以极大地影响这些过程。硼既能作为硼烷路易斯酸来活化金属-N 配合物,又能作为双齿亲核试剂硼烯来活化游离的 N 原子。后一种情况既能接受又能提供电子密度,这让人联想到同时含有满和空 d 轨道的过渡金属体系。
