Photolysis of 5,5'-dimethyl-2,2'-dinitrodophenylmethanes (1) in propan-2-ol yielded 2,9-dimethyl-11H-dibenzodiazepin-11-one 5-oxides (2) as the major product. 5-Methyl-3-(5'-methyl-2'-nitrophenyl)-2,1-benzisoxazoles (3), 2,9-dimethyldibenzodiazepin-11-ones (4), 2,2'-dinitrobenzophenones (5), acridinones (6), N-hydroxyacridinones (7), dibenzodiazepin-11-one 5,6-dioxide (8) and 2,2'-dinitrosobenzophenone (9) were also formed in varying amounts.Irradiation of (1) in acidic ethanol afforded benzisoxazoles (3) as the major product.In benzene medium, the major photoproduct of (1) was 2,2'-dinitrobenzophenones (5).Irradiation of (1) in triethylamine afforded dibenzodiazepines (12) also in addition to the other products.A plausible mechanism to account for the formation of various products in these photoreactions is discussed.
