X-Ray study of a new heterocycle: the crystal structure of 1,2-dibromo-1,2-diphenyl-1,2-dihydroazeto[1,2-a]pyridinium chlorate
Abstract
Formation of the hitherto unknown dihydroazeto[1,2-a]pyridinium ring system obtained by bromine oxidation of 2-aminoimidazo[1,5-a]pyridinium salts is confirmed by single-crystal X-ray analysis.
