Metal complexes of maleimide compounds
The metal complexation ability of some N-substituted maleimides containing a carboxyl group was investigated. Thus, N-(4-carboxy-phenyl)-maleimide, N-(3-acetoxy-4-carboxy-phenyl)-maleimide and poly[N-(3-acetoxy-4-carboxy-phenyl) -maleimide] were prepared and complexed with several transition metals, such as Co2+, Ni2+ and Cu2+. The formation of complexes which separated as precipitates from the reaction mixtures was confirmed by elemental and spectral analyses. The thermal stability of the complexes was evaluated by thermogravimetry.
