N,N-Diisopropylethylamine mediates a cathodic reduction approach for the hydrogenation of azobenzenes in dichloromethane as hydrogen source. The reaction proceeded smoothly in a simple undivided cell under constant-current electrolysis. A series of azobenzenes were successfully reduced to the corresponding hydrazobenzenes in good yields at room temperature.
