Although the metathesis of metal–boron double bonds with elemental chalcogenides is an established process, no similar reactivity has been observed with element–nitrogen bonds. Such a reaction would provide a new route to iminoborane compounds (RB≡NR′), which have recently experienced renewed synthetic interest. Herein, we present the first observation of M=B/C=N metathesis reactions, which led to the isolation of a stable iminoborane in addition to further iminoborane cycloaddition products.

M = B / C = N键易位合成亚氨基硼烷

尽管金属-硼双键与元素硫属元素化物的易位是一个既定过程，但没有观察到与元素-氮键相似的反应性。这样的反应将为获得亚氨基硼烷化合物（RB≡NR'）提供新途径，该化合物最近经历了新的合成兴趣。在本文中，我们首次观察到M = B / C = N复分解反应，除了进一步的亚氨基硼烷环加成产物外，还导致分离出稳定的亚氨基硼烷。
