Reinvestigation of the electrochemical reduction of 1,2-dibromobenzene by polarography, cyclic voltammetry, rotating ring-disk electrode voltammetry and controlled potential electrolysis, as well as theoretical calculations, leads to the proposal of a stepwise mechanism. Experimental results for bromobenzene and 1,3-dibromobenzene are also reported for comparison.
