The reduction of vicinal dibromoalkanes is investigated as an example of the dichotomy between outer-sphere and inner-sphere processes in reductiveelimination. As a result from the analysis of the kinetic data, outer-sphere reagents such as carbon electrodes and aromatic anion radicals react with vicinal dibromoalkanes according to an «ET» mechanism in which the rate-determining step is a concerted
