In contradiction to the experience the hydrodimer is formed as the main product in the electroreduction of coumarine using lithium compounds as a supporting electrolyt.It is assumed that the lithium ions are coordinated internally with the radicalanion A resp.B derived from coumarine.In this way the hydrodimerization is favoured.From 18 different compounds added as possible mediators to the catholyt only pyridine influences moderately the ratio: hydrodimerization product/dihydroproduct. - Keywords: Hydrogen Transfer, Coumarine, Electroreduction
