Benzyl chloride reduction was studied in a powder macroelectrode (PME) made of silver, graphite or silver/graphite mixtures (1:3, 1:1 and 3:1) in absence of solvent, or using a very low amount of DMF as solvent (PhCH 2 Cl/DMF 3:1). A 0.1 mol L −1 K

Benzyl halides adsorbed on a cathode made of pure or silver-doped graphite powder were reduced in an undivided cell using an aqueous electrolyte and an inert anode, in the absence or presence of benzaldehyde. The product ratio is influenced by the ap

The main challenge in organic synthesis is the formation of new C-C bonds in order to construct more complex carbon skeletons in a defined arrangement. In contemporary electrochemical publications, such C-C couplings are still a minor subject 1 . Her

A new synthetic method of reductive methylation promoted by electrolysis in aqueous medium was studied in this work. The method is based on the reduction of iminium ions generated in situ from the condensation of amines with formaldehyde. Besides the

Mixtures of carbonyl compounds and allyl halides, adsorbed on a graphite powder cathode, were reduced under aqueous anolyte to give high yields of homoallylic alcohols. Catalytic amounts of silver or tetrabutylammonium tetrafluoroborate improved the

A green electrochemical heterocoupling procedure has been developed. Prenyl halides and benzaldehyde adsorbed on a graphite powder cathode were reduced in a cavity cell using aqueous anolyte, providing isomer mixtures of prenylated alcohols. High α-
