Synthesis of Urethanes and Azidocarbonyls of 1,2,3-Triazole Series

By the reaction of 4-carboxy-1,2,3-triazoles and 4-carboxy-1,2,3-triazole-1-oxide with diphenyl-phosphoryl azide in alcohol in the presence of triethylamine a series of the corresponding triazoleurethanes is obtained. In the presence of water, along with urethanes, symmetrically substituted triazolylureas are formed. By the reaction of sodium azide with 4-chloroformyl-1,2,3-triazole-1-oxides, as well as by nitrosation of hydrazides of acids 4-azidocarbonyl-1,2,3-triazole-1-oxides are obtained.

1,2,3-Triazole N-Oxides. II. Synthesis of Substituted 4(5)-Ethoxycarbonyl-1,2,3-triazole N-Oxides

Oxidative cyclization of ethyl 2-hydrazono-3-hydroxyimino- and 3-hydrazono-2-hydroxyiminobutanoates in the presence of γ-MnO2 yields isomeric 4(5)-methyl-2-phenyl-5(4)-ethoxycarbonyl-1,2,3-triazole 1-oxides. Alkaline hydrolysis and ammonolysis
