Abstract

Isomeric 3-(nitrophenyl)-1, 2, 4-triazole-5-thiones are synthesized by cyclizing 1-nitrobenzoylthiosemicarbazides. 1-(4-Nitrophenyl)-1, 2, 4-triazole-3-thione is prepared by condensing 4-(4-nitrophenyl) thiosemicarbazide with formic acid. Oxidation converts the triazolethiones to nitrophenyltriazoles, and the latter are reduced to aminophenyltriazoles.
