The complex (cod=1,5-cyclooctadiene) reacts with Ph2PCH2PPh2 (dppm) to yield the cationic A-frame organoplatinum(II) dimer, Cl.The phenyl and methyl analogues yield both mononuclear and the corresponding dimeric products.Previous work on the methylplatinum complex is not substantiated by these results.

Reactions of [PtXY(cod)] (X = Y = Cl, Me, Ph; X = Cl, Y = Ph, COPh) with bulky monodentate and chelating group 5B ligands have been examined by 31P{1H} NMR spectroscopy. The molecularity of the products is a function of steric bulk with monodentate ligands and a function of chelate bite with bidentate ligands. The geometry of the products is controlled largely by the trans influence of both neutral and anionic groups. Where the steric constraints involved in nucleophilic attack of the complexes by bulky ligands are dominant, olefin displacement can be prevented entirely. Reactions of [PtXYL2] (X = Y = Ph, Cl; X = Ph, Y = Cl; L = monodentate ligand, L2 = bidentate ligand) with carbon monoxide have been studied by 31P{1H} and 13C{1H} NMR and infrared spectroscopies. The mechanism of carbonyl insertion at platinum(II) is discussed in terms of the chelate effect and the trans influence of the anionic ligands.
