Abstract With the reaction of bis(1,5‐cyclooctadiene)nickel(0) and trans ‐penta‐2,4‐dienoic acid in the presence of tricyclohexylphosphine, a new more general method was developed to synthesize cyclic π 3 ‐allyl‐carboxylato Ni(II) complexes, which are known to be intermediates in the CC coupling of butadiene and CO 2 . The cyclic π 3 ‐allyl‐carboxylato Ni(II) complex obtained is tested as a mediator in the electrochemical coupling reaction of butadiene and carbon dioxide. We also demonstrate the dependency on the coordination sphere by using platinum instead of nickel as the metal center. Copyright © 2005 John Wiley & Sons, Ltd.
