Trialkylalanes, which are inert toward imines, undergo addition to them in the presence of a catalytic amount of dichlorodicyclopentadienylzirconium(IV) (Cp2ZrCl2). The reaction tolerates the presence of several functional groups in the starting imine such as halo, amide, nitrile, and hydroxy groups. A possible reaction pathway is proposed involving metallacyclic intermediates.
三烷基醛对亚胺是惰性的,在催化量的二氯二环戊二烯基锆(IV)(Cp2ZrCl2)的存在下,三烷基醛会与亚胺发生加成反应。该反应可以容忍起始亚胺中存在卤代、酰胺、腈和羟基等多个官能团。提出了一种涉及金属环中间体的可能反应途径。
