The generation of Ni(PPh₃)₄ by electrochemical reduction was carried out in a divided cell containing NiCl₂(PPh₃)₄, PPh₃ and n-Bu₄NBr in DMF with a lead plate as cathode and a platinum plate as anode under the stream of argon at 60°. Using this Ni(PPh₃)₄, biphenyls and the heterocyclic compounds were synthesized in fairly good yields.
