Abstract
Trialkylalanes, which are inert toward imines, undergo addition to them in the presence of a catalytic amount of dichlorodicyclopentadienylzirconium(IV) (Cp2 ZrCl2 ). 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.
Key words
zirconium - catalysis - trialkylalanes - amine synthesis - imines

10 Ketimines proved to be inert toward Et3 Al in these conditions.
