Room-temperature ionic liquids as new solvents for organic electrosynthesis. The first examples of direct or nickelcatalysed electroreductive coupling involving organic halides

Direct or Ni-catalysed electroreductive homocouplings of organic halides and couplings of organic halides with activated olefins are efficiently conducted by constant current electrolyses in an undivided cell in room-temperature ionic liquids as the solvent–electrolyte media.
