The well‐defined three coordinated electronically unsaturated cationic organoaluminum complex [((2,6‐iPr2C6H3N)P(Ph2)}2N)AlMe]+[MeB(C6F5)3]− (1), has been utilized to catalyze the cyanosilylation of aldehydes and ketones undermild and solvent‐free conditions. Moreover, catalyst 1 showed high chemoselective cyanosilylation of aldehydes over ketones, nitriles and olefins. The multinuclear NMR investigations
定义明确的三配位电子不饱和阳离子有机铝络合物[[(2,6 - i Pr 2 C 6 H 3 N)P(Ph 2)} 2 N)AlMe] + [MeB(C 6 F 5)3 ] −(1)已用于在温和无溶剂条件下催化醛和酮的氰基硅烷化反应。此外,催化剂1显示醛在酮,腈和烯烃上的高化学选择性氰基硅烷化。该多核NMR调查显示经由之间路易斯加成物形成的是硅氰化反应进行1 然后激活TMSCN(Si-CN键),然后在活化硅烷的Si中心对羰基氧进行亲核攻击并形成产物。
