The oxidative addition of ArHgX (Ar=Ph, X=Cl; Ar=C6F5, X=Br) to the nickel complex (Ph3P)4Ni resulting in formation of ?-aryl derivatives of bivalent nickel, (Ph3P)2Ni(Ar)X, has been performed.It was found that the reaction between (Ph3P)4Ni and (C6F5)2Hg yields the bimetallic compound (Ph3P)2Ni(C6F5)HgC6F5.Similarly, the reaction between <(C6F5)3Ge>3Hg and (Ph3P)4Ni gives (Ph3P)2NiHgGe(C6F5)3, containing a Ge-Ni-Hg-Ge chain.A five-membered metallocycle with a N -> Ni chelate bond was obtained from the reaction of (Ph3P)4Ni with 8-(α-bromomercuriethyl)quinoline.
