A conversion of o-phenylenediamines into benzotriazoles was achieved at room temperature using tert-butyl nitrite. The optimized conditions are also well suited for the transformation of sulfonyl and acyl hydrazines into corresponding azides. This protocol does not require any catalyst or acidic medium. The desired products were obtained in excellent yields in a short span of time.

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.
