1,3,2‐diazaphospholenes catalyze metal‐free transfer hydrogenation of a NN double bond using ammonia–borane under mild reaction conditions, thus allowing access to various hydrazine derivatives. Kinetic and computational studies revealed that the rate‐determining step involves simultaneous breakage of the BH and NH bonds of ammonia–borane. The reaction is therefore viewed as a concerted type of
1,3,2-二氮杂磷烯在温和的反应条件下使用氨硼烷催化NN双键的无金属转移加氢反应,因此可以得到各种肼衍生物。动力学和计算研究表明,确定速率的步骤涉及同时破坏氨硼烷的BH和NH键。因此,该反应被认为是协同作用的氢解反应。
