Abstract
The corresponding 2-arylhydrazono-3-oxoimidazo[1,2-a]pyridines, 3-arylhydrazono-2-oxoimidazo [1,2-a]benzothiazoles, 2-oxoimidazolidino[3,2-a]benzimidazoles, 2-oxoimidazo[1,2-a]benzoxazoles, and 2-arylhydrazono-3-oxothiazolo[2,3-a]benzimidazoles were obtained by the condensation of arylazochloroacetyl chlorides with 2-aminopyridine, 2-aminobenzothiazole, 2-aminobenzoxazole, 2-aminobenzimidazole, and 2-mercaptobenzimidazole. 5-Arylhydrazono-1,2-diphenylimidazole-4-ones and 5-arylhydrazono-3,4-diaryl-1,2,4-oxidiazine-6-ones were synthesized by the reaction of arylazochloroacetyl chlorides with N-phenylbenzamidine and N-phenylamidoxime.
