Preparative methods were developed for the production of 4-amino- and 4,5-diamino-2-phenyl-1,2,3-triazoles by cyclization of 2-nitro-2-phenylhydrazonoacetaldoxime, 2-nitro-2-phenylhydrazonoacetamide oxime and its acetate, and 2-phenylazo-2-phenylhydrazono

Potassium and silver nitrite add to 1-methoxy-2-phenyltriazolium salts as ambident nucleophiles to give 4-nitro- and 4-hydroxytriazoles.If unsubstituted, the latter, via nitrosation and oxidation, affords 4-hydroxy-5-nitro-2-phenyltriazole.The hydroxytriazoles add to unchanged starting material producing bistriazolyl ethers.A nitro-substituted derivative of the latter displays photochromic properties.
