REACTIONS OF PHENYL-SUBSTITUTED HETEROCYCLIC COMPOUNDS: I. NITRATION OF 2-PHENYL-1,2,3,2H-TRIAZOLE

Abstract

Structures have been assigned to the mono-, di-, and tri-nitration products of 2-phenyl-1,2,3,2H-triazole, on the basis, partly, of ultraviolet absorption spectra. The pattern of nitration closely resembles that of 1-phenylpyrazole. A compound previously described as 2-(o-nitrophenyl)-1,2,3,2H-triazole is actually 4-nitro-2-p-nitrophenyl-1,2,3,2H-triazole.
