The zerovalent platinum dimer [Pt2(μ-CO)(CO)2(μ-dppm)2] (1) (dppm = Ph2PCH2PPh2) has been prepared from [Pt2Cl2(μ-dppm)2] (2) via sodium borohydride reduction under carbon monoxide and from [Pt2(μ-dppm)3] (3) by substitution of a dppm ligand with CO. This latter reaction is readily reversible and can undergo several cycles of carbonylation-decarbonylation. Complex 1 undergoes typical oxidative addition reactions; it is readily protonated to yield [Pt2(H)(CO)(μ-dppm)2]-(p-CH3C 6H4SO3)·C6H6 (4). With I2, 1 reacts to yield [Pt2I2(μ-dppm)2] (5), and reaction with CH3I produces [Pt2(μ-I)(CH3)2(μ-dppm)2]I (6).

The first alkyldiplatinum(I) complexes containing β-hydrogen atoms, - (R=Et, CD3CH2, Pr, or Bu; dppm=Ph2PCH2PPh2), were prepared by reaction of with RI followed by addition of K.The complexes were yellow, air-stable solids which were characterized by 1H and 31P n.m.r. spectroscopy.Photochemical or thermal decomposition of the ethyl derivative was shown to involve β elimination, which occured subsequent to the rate-determining step.
