A simple and efficient method for preparation of 5-aryloxy tetrazoles (3a-h) from arylcyanates (1a-h) with using ZnCl2/AlCl3/silica (ZAS) as an effective heterogeneous catalyst in solvent free are described with excellent yields and high purity. The rate of product formation was enhanced by introduction of electron donating substituents. The 1H NMR and chemical shifts and multiplicities are also discussed.
