Abstract
Abstract1-Benzyl-2-hydrazinobenzimidazole undergoes autooxidative coupling with nitroformaldehyde arylhydrazones to give meso-carbon-unsubstituted 1-(1-benzyl-2-benzimidazolyl)-5-arylformazans (instead of the expected formazans with a nitro group in the meso position). Data on the structures and complexing abilities of the new unsymmetrical formazans of the benzimidazole series are presented.
