Abstract
A high quality 1,2,3-triazole is obtained in a one pot two step reaction between appropriately substituted hydrazide derivatives, dihaloethanediol and NH.sub.3 in methanol. Synthesis of various N.sub.1 -alkyl, N.sub.1 -aryl, and N.sub.1 -heterocyclic-1,2,3-triazoles is also accomplished following the same general procedure.
