Description / Table of Contents:
Reaction of 3-Acetyl-2,5-dianilino-1,4-benzoquinone and N1-Phenylbenzamidine; a Synthesis of Quinolinequinones4,6-Dianilino-2-phenylquinoline-5,8-quinone (3a) is the main product of the reaction of 3-acetyl-2,5-dianilino-1,4-benzoquinone (1a) and N1-phenylbenzamidine (2a); byproducts are 4,8-dianilino-2-phenylquinoline-5,6-quinone (4). 4-acetyl-6-anilino-5-hydroxy-2-phenylbenzoxazole (5a) and the corresponding 1,2-diphenylbenzimidazole 6. The structures and reaction-mechanism are confirmed by chemical reactions and spectroscopic data (MS, 1H-NMR, IR, UV).
