摘要：

Treatment of a secondary amine (piperidine or N-benzylmethylamine) with sequentially trimethylaluminum and carbodiimide CyN=C=NCy in a molar ratio of 1:1:1 afforded two mononuclear guanidiriatoaluminum complexes, [{(C5H10N)C(NCy)(2)}AlMe2] (1) and. [{(Bz(Me)N)C(NCy)(2)}AlMe2] (2). Introducing dry oxygen slowly into the solution of 1 or 2, [{(C5H10N)C(NCy)(2)]AlMe(mu-OMe)](2) (3) and [{(Bz(Me)N)C(NCy)(2)} AlMe( mu-OMe)](2) (4) were obtained, respectively. Both of 3 and 4 were also prepared by treatment Of piperidine or N-benzylmethylamine with trimethylaluminum and carbodiimide CyN=C=NCy in the presence of O-2. The complexes 1-4 were characterized by H-1,C-13 NMR spectra and single crystal X-ray diffraction analysis. 1-4 were also used to catalyze the Meerwein-Ponndorf-Verley (MPV) reaction.
