Activation of N-H bonds by a molecular aluminum complex via metal-ligand cooperation is described. ((Ph)I2P(2-))AlH (1b), in which (Ph)I2P(2-) is a tridentate bis(imino)pyridine ligand, reacts with anilines to give the N-H-activated products ((Ph)HI2P(-))AlH(NHAr) (2). When heated, 2 releases H2 and affords ((Ph)I2P(-))Al(NHAr) (3). Complex 1b catalyzes the dehydrogenative coupling of benzylamine to afford H2, NH3, and N-(phenylmethylene)benzenemethanamine.
描述了通过分子铝配合物的金属-配体协同作用激活 N-H 键。((Ph)I2P(2-))AlH（1b），其中(Ph)I2P(2-)是一个三齿双（亚氨基）吡啶配体，与苯胺反应生成 N-H 活化产物((Ph)HI2P(-))AlH(NHAr)（2）。加热时，2 释放出 H2，并得到((Ph)I2P(-))Al(NHAr)（3）。配合物 1b 催化苄胺的脱氢偶联，生成 H2、NH3 和 N-(苯基亚甲基)苯甲胺。
