- SYNTHESIS OF SOME CONDENSED s-TRIAZOLE HETEROCYCLES USING PHASE-TRANSFER CATALYSIS TECHNIQUE
-
Some condensed heterocyclic systems were obtained by reacting 3-phenyl-4-amino-s-triazole-5-thiol 1 as a dianionic ambident compound containing N- and S- poles with some tetrahalo- and dihalo derivatives as well as α-haloketones and
