Abstract

N-Phenylmaleimide and N-phenyl-2,3-dimethylmaleimide have been synthesized and structurally characterized by X-ray diffraction. The crystal structure of the second compound proves that condensation of PhNH₂ with 2,3-dimethylmaleic anhydride gives, through a one step mechanism, N-phenyl-2,3-dimethylmaleimide and not the corresponding isomaleimide.

Keywords
