An electroreductive "Barbier Type" allylation of imines with ally1 bromide has been performed in a PbBqJ3uqNBqTI-G(Al anode)-(Pt cathode) system. A combination of Pb(O)/Pb(II) redox and a sacrificial aluminum anode works as a mediator for both cathodic and anodic electron transfer processes, respect
