A nickel oxyhydroxide [NiO(OH)] anode was exploited to develop a new synthetic route for the electrocatalytic N-N homocoupling of N-alkylaminopyrazoles in an alkaline aqueous medium. The advantages of this green electrochemical methodology include low cost, atom economy and high yields. (C) 2018 Elsevier Ltd. All rights reserved.

Oxidation of C-amino-N-alkylpyrazoles on a NiO(OH) electrode in an aqueous alkaline medium affords the corresponding azo-pyrazoles. The success in implementation of these processes is due to the structure of C-aminopyrazoles.
