摘要
Facile synthesis of 5-substituted 1H-tetrazoles was achieved by treating nitriles with NaN3 in water or toluene in the presence of tetrabutylammoniumhydrogen sulfate (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.
