Abstract

A simple and efficient method is described for the preparation of 5-aryloxytetrazoles in excellent yields and high purity from aryl cyanates using silica sulfuric acid as catalyst. The rate of product formation was enhanced by introduction of electron-donating substituents. The 1H NMR spectral characteristics of the products also are discussed.
