Microwave-assisted solid phase diazotation: a method for the environmentally benign synthesis of benzotriazoles

Author affiliations

Abstract

A novel environmentally benign approach based on microwave-assisted solid phase diazotation to convert o-phenylendiamines to substituted benzotriazoles is described. Excellent yields were obtained for a phenylenediamines proving the efficacy of the method. The reaction was carried out in the solid phase under microwave irradiation taking advantage of the strong microwave absorption capability of K-10 montmorillonite that acted as a catalyst and medium in one. The catalyst is recyclable, and the reaction occurs with high efficiency and does not produce any harmful waste.
