A REGIOSPECIFIC SYNTHESIS OF 1-HETEROCYCLIC SUBSTITUTED 1,2,4-TRIAZOLES VIA ADDITION REACTION OF 1,2,4-TRIAZOLE WITH FUNCTIONALIZED CARBODIIMIDE

ABSTRACT The reaction of 1,2,4-triazole with functionalized carbodiimide 2 or 6 under solid K2CO3 provide a convenient and regiospecific route to 1-(2-imidazolonyl)-1,2,4-triazole 4 or 1-(2-quinazolonyl)-1,2,4-triazole 8.
