Abstract

Treatment of quinonemonoimines and an N-phenylquinonediimine of the pyrido[1,2-a]benzimidazole series with 1,3-indanedione, barbituric acid, or malononitrile and also with thioglycolic acid gives mono substitution at the 8 position. On the other hand, reaction of the N-cyclohexylquinonediimine in this series with C-nucleophiles leads to monosubstitution at position 9.
