DERIVATIVES OF 1,4,5,8-NAPHTHALENETETRACARBOXYLIC ACID. III. AMINOLYSIS OF 1,4,5,8-NAPHTHALENETETRACARBOXYDIIMIDE AND ITS DERIVATIVES

When heated with ammonia, aliphatic amines, or aromatic amines more basic than those forming an imide ring, N,N'-diaryl-2-chloro-1,4,5,8-naphthalenetetracarboxydiimides form products from transamidation, preferentially in one imide ring, in addition to su
