Hydrogen-1, carbon-13, and aluminium-27 nuclear magnetic resonance studies of complex formation between aluminium isopropoxide and ethylenediamine

Abstract

The interaction of [Al(OPrⁱ)₃]₄ with ethylenediamine in benzene solution has been studied using ¹H, ¹³C, and ²⁷Al n.m.r. spectroscopy. The initial products appear to be a linear diadduct and a polymer, but other unidentified aluminium compounds may also be formed. There is no evidence to support the suggestion that significant amounts of complexes are formed containing five-co-ordinate aluminium.
