Abstract

A method for copper(II)-mediated N–N bond formation of N-imidoylisothioureas has been developed for the synthesis of 1,2,4-triazoles. The reaction requires cerium(IV) sulfate as an oxidant and proceeds at room temperature. This approach provides access to a variety of substituted 1,2,4-triazoles.
