[PtPh2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) reacts with equimolar [PtCl2(cod)] (cod = 1,5-cyclooctadiene) to give a mixture of [PtPh2(cod)] (38%), [PtCl(Ph)(cod)] (53%) and [PtCl 2(dppe)] (72%) via exchange of the phenyl and chloro ligands among the Pt complexes. The reaction is strongly inhibited by addition of Cl -. The intermolecular phenyl ligand transfer from Pd to Pt is observed in the reaction of [PdCl(Ph)(bpy)] (bpy = 2,2′-bipyridine) with [PtX2(cod)] (X = Cl, I), which produces [PtX(Ph)(cod)]. The reaction of [PdCl(Ph)(bpy)] with [PdCl2(cod)], giving [Pd2(μ -Cl)2 {(4,5-η-κC1)-(C8H 12Ph)}2], occurs much faster than a similar reaction of [PdCl(Ph)(bpy)] with [PtCl2(cod)]. [PtPh2(L2)] (L2 = cod, dppe) reacts with [PdCl2(cod)] in CH 2Cl2 at room temperature to afford [Pd2(μ -Cl)2{(4,5-η-κC1)-(C8H 12Ph)}2] via intermolecular phenyl ligand transfer from Pt to Pd and subsequent insertion of a C=C bond of cod into the Pd-Ph bond. Cationic Pd complexes [Pd(acetone)2(cod)]2+(BF 4-)2 and [Pd(η3-C 3H5)(acetone)2]+(BF4-) react with [PtPh2(cod)] to form biphenyl. All these results indicate that chloro complexes of Pd and Pt with cod ligand undergo the ligand exchange with the phenyl complexes of these metals.
