N-(Arylmethyleneamino)phthalimides (2a-c) carrying an o-substituent in the aryl group were prepared by the reaction of N-aminophthalimide with o-substituted benzaldehydes.The reaction of these compounds with Grignard reagents proceeded either by normal addition to one of the carbonyl groups to give 3a-c or by addition and cleavage to give 4-arylphthalaz-1-ones 5a-c.The steric effect exhibited by either the Grignard reagent or the N-arylmethylene compound was studied.The reaction of N-furfurylideneaminophthalimide (2d) with Grignard reagents was also investigated.N-( Arylmethyleneamino)phthalimides reacted with primary amines to give N,N'-dialkylphthalamides (7a and b) while the reaction with secondary amines gave (8a and b).
