N-Arylmaleisoimidium perchlorates (1a and b) were prepared by the action of acetic anhydride and perchlorid acid on the N-arylmaleamic acids (2a and b).Compound 1b reacted with amines via ring-opening to give N,N-disubstituted maleamides (4a-c), while the reaction of 1a with secondary amines gave N-phenylmaleimide (6).The reaction of 1a and b with aromatic hydrocarbons in the presence of anhydrous aluminium chloride gave good yields of trans-β-aroyl-N-arylacrylamides (7a-h).The reactions of some of the latter compounds with amines and phenylhydrazine are also discussed.
