The indirect electroreduction of chlorinated benzenes and dibenzofurans in methanol has been investigated. (2,2'-Bipyridyl)nickel(II) chloride (1) and (1,4,8,1 1-tetraazacyclotetradecane) nickel(II) chloride (2) were used as mediators for the electron transfer. The electrolyses were carried out potentiostatically at -1.4V vs. Ag/AgBr in a divided batch cell. Indirect reduction of more highly chlorinated benzenes lead to chlorobenzene as the main product. In case of the chlorodibenzofurans, reduction to unsubstituted dibenzofuran was achieved. Much higher selectivity in the mediated electroreduction as compared with the direct cathodic reduction is observed. In particular the formation of hydrogenated products is completely suppressed.
