Article abstract of DOI:10.1021/jo00048a042

N-Substituted 2,2,2-trifluoroethanimidic acid 1-methylethylidene hydrazides have been prepared and allowed to react with tert-butyl hypochlorite in CH2Cl2.N-Aryl, N-alkyl, and N-(methoxycarbonyl)amidrazones 2-4 undergo three types of cylizations via the i
