N-Arylphthalisoimidium perchlorates (1a, 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 1a wtith phenylmagnesium bromide involved just deprotonation to the isoimide (9) followed by rearrangement to N-phenylphthalimide (8).
