Abstract

In reactions with 3-chloro-3-phenylphthalides, aromatic amines attack the primary and tertiary carbon atoms to give a mixture of 2-aryl-3-hydroxy-3-phenylisoindolinones and 3-arylamino-3-phenylphthalides. The effect of the nucleophilicity of the amine on the primary direction of attack was studied. The ring-chain tautomerism of 3-arylamino-3-phenylphthalides and 2-benzoylbenzoic acid arylimines was studied by IR and UV spectroscopy.
