Synthesis of ?-Ketoamine Derivatives of Aluminum

Abstract
Aluminium isopropoxide reacts with β-ketoamines (CH3C(O)CHC(NHR)CH3, R = ethyl, n-propyl, n-butyl) in benzene to give the mono-, bis-, and tris- ketoamine complexes of aluminium (depending on the ratio of reactants) in a clean, high-yield reaction. The hydrolytically unstable products are relatively volatile, soluble and monomeric in benzene. The infrared spectra of the complexes are reported.
