QUATERNARY 1-AMINOBENZIMIDAZOLIUM SALTS IN REACTIONS WITH β-DICARBONYL COMPOUNDS. FORMATION OF PYRIDAZINO/1,6-a/BENZIMIDAZOLIUM CATIONS AND 1-ARYLPYRAZOLES

Pyridazino/1,6-a/benzimidazolium cations and 1-(o-methylaminoaryl)-4-acetylpyrazoles are formed simultaneously in approximately equal amounts in the reaction of excess acetylacetone with quaternary 1-aminobenzimidazolium salts in aqueous potassium carbonate solution.Mesoionic pyridazinobenzimidazoles and the corresponding 4-ethoxycarbonylpyrazoles were obtained with acetoacetic ester under similar conditions.
