Isoimides of benzene-1,2-dicarboxylic acid and napthalene-1,8-dicarboxylic acid. Suitable conditions for preparation
N-Arylisophthalimides are formed in an aprotic solvent at 20°C from equivalent quantities of phthaloyl chloride and an arylamine in the presence of not less than 1 mole of a dehydrochlorinating reagent. N-Nitrophenylisonaphthalimides were obtained by the reaction of an equimolar mixture of naphthaloyl chloride and nitroanilines in boiling toluene.
