A series of novelpyrazolyl tetrazoles were synthesized by introducing tetrazole moiety at the fourth position of 1,3-substituted pyrazole nucleus. Synthesis was carried out by cyclization of different pyrazolonitriles using sodium azide in the presence of triethylammonium chloride as phase transfer catalyst. The structures of the synthesized compounds were confirmed on the basis of physical and spectral
