Facilesynthesis of 5‐substituted 1H‐tetrazoles was achieved by treating nitriles with NaN3 in water or toluene in the presence of tetrabutylammoniumhydrogensulfate (TBAHS). The reaction could be carried out in water as well as in toluene. The procedure is environment‐friendly, practical, and provides excellent yield of tetrazoles.

Novel ligands for the HisB10 Zn2+ sites of the R-state insulin hexamer that are capable of prolonging the action of insulin preparations are disclosed.
A simple, new and convenient metal free procedure for the synthesis of 5-substituted 1H-tetrazoles using various nitriles and sodium azide in the presence of urea and acetic acid with good to highyields is developed. The reaction plausibly proceeds through in situ formation of urea azide active complex without toxic and/or expensive metal catalysts.
