The electrochemical reduction of phenyldiazonium and phenyl-bis-diazonium cations on mercury drop and platinum cathodes exhibits a multistep nature, as demonstrate the results of polarographic and cyclic voltammetry measurements. The primarily formed radicals participate in various secondary processes, as a result of which occur species absorbing UV-VIS radiation. Electronic absorption in the visible region can be ascribed to entities forming from the recombination of two azophenyl or azophenyl and phenyl radicals, originating from the one- or two-electron reduction of primarily or secondary formed cations.
