2,4-dimethyl- (I-a), 2-methyl-4-phenyl- (I-b), and 2,4-diphenyl-1,5-benzodiazepine (I-c) were irradiated with a high-pressure mercury arc under an oxygen atmosphere in benzene and in acetic acid. In all cases oxidative ring-contraction products, 2-acylquinoxalines (II), were obtained. It was found that there was a solvent effect in these reactions ; <I>e.g</I>., in benzene the diazepine (II-d) leads to 2-benzoyl-3-methylquinoxaline (II-d), while in acetic acid it leads to 2-acetyl-3-phenyl-quinoxaline (II-b).
