摘要：

Treatment of the imines [ArN=CH-CH=NAr] and [ArN=CH-2-py] (Ar=2,6-Pr-2'C6H3) with AlMe3 in toluene affords the highly crystalline complexes [AlMe3{ArN-CH2-C(Me)=NAr}] (1) and [AlMe2{ArN-CH(Me)-2-py}] (2); the molecular structures of 1 and 2 show that the aluminiums are bonded to imino-amide and pyridyl-amide ligands respectively arising from methyl group transfer from the aluminium centre to the backbone carbon of the imine ligand.
