N-Arylphthalisoimidium perchlorates (1 a, b) react with primary amines via ring-opening to give N,N′-disubstituted phthalamides (3a—d). They react with aromatic hydrocarbons under Friedel-Crafts conditions to give 2,3-diaryl-3-hydroxyphthalimidines (a—i) while the reaction of 1 a with phenylmagnesium bromide involved just deprotonation to the isoimide (9) followed by rearrangement to N-phenylphthalimide (8).
