Reaction of [PtPh2(cod)] or [PtClPh(cod)] with (Ph2PC5H4)2ZrCl2 yields the Ph2PC5H4-bridged species [PtXPh(Ph2PC5H4)2ZrCl2] (X = Ph, Cl). Treatment of [PtPh2(cod)] or [PtClPh(cod)] with 2 equiv of PhP(C5H4)2ZrCl2, prepared by reaction of [ZrCl4(THF)2] with (TlC5H4)2PPh, yields cis- [PtPh2{PhP-(C6H4)2ZrCl 2}2] or trans-[PtClPh{PhP(C5H4)2ZrCl2} 2]. Each of the mixed-metal complexes has been isolated as an air-sensitive solid and characterized by elemental analysis and NMR spectroscopy. [PtPh2-(Ph2PC5H4) 2ZrCl2] does not react with carbon monoxide, and cis-[PtPh2{PhP(C5H4)2ZrCl 2}2] undergoes a slow displacement of phosphine by CO, whereas the two chlorophenylplatinum complexes undergo smooth carbonylation to the corresponding benzoylplatinum species.
Carbonylation of phenylplatinum(II) complexes containing bidentate ligands

A series of complexes of the type [PtClPh(P Y)] (P Y = 1,2-bis(diphenylphosphino)ethane (dppe), 1-(diphenylphosphino)-2-(diphenylarsino)ethane (appe), 1,3-bis(diphenylphosphino)propane (dppp), 1-(diphenylphosphino)-2-(methylthio)ethane (PC2S), or 1-(diphenylphosphino)-2-(dimethylamino)ethane (PC2N)) has been prepared and the carbonylation reactions of these complexes investigated. The corresponding benzoyl complexes have been generated by an alternative route. No reaction of [PtClPh(P Y)] with CO takes place when P Y = dppe or appe, but carbonylation proceeds smoothly, albeit slowly, when P Y = dppp, PC2S, or PC2N. The reaction is most rapid for the dppp complex. These results are rationalized in terms of both dissociative and nondissociative reaction pathways.
