  use of sterically hindered [Pt(PtBu3)2] (1) to access Pt/Zn bimetallic complexes. Compounds [(PtBu3)2Pt → Zn(C6F5)2] (2) and [Pt(ZnCp*)6] (3) (Cp* = pentamethylcyclopentadienyl) were isolated by reactions with Zn(C6F5)2 and [Zn2Cp*2], respectively. We also disclose the cooperative reactivity of 1/ZnX2 pairs (X = Cl, Br, I, and OTf) toward water and dihydrogen, which can be understood in terms of bimetallic

  A new preparative route to hydrido-platinum(II) complexes, particularly those containing bulky phosphines which are inaccessible by other methods, involves the convenient reaction of phosphines with bis [(2-methoxy-5-cyclooctenyl)chloroplatinum] in methanol. A β-hydrogen elimination mechanism is described, as well as the preparation and use as hydrogenation catalysts of the complexes trans-[(2-CH3O-5-C8H12)Pt(L)Cl]

• Platinum-Catalyzed Phenyl and Methyl Group Transfer from Tin to Iridium:  Evidence for an Autocatalytic Reaction Pathway with an Unusual Preference for Methyl Transfer

  Platinum complexes have been found to catalyze the transfer of U-bound ligands to the Ir center in CP*(PMe3)IrCl2 (Cp* = eta(5)-C5Me5) from Bu3SnPh and PhxSnMe4-x (x = 0-3) complexes. Despite the presence of Sn-Ph bonds in the PhxSnMe4-x complexes, exclusive transfer of the Sn-Me group occurs, an unusual chemoselective process. Examination of the reaction mechanism supports an autocatalytic process.

  The reaction of Pt(PiPr(3))(3) with SO2 led to the formation of (PiPr(3))(2)Pt(SO2) (1), isolated in 93% yield. The addition of [H(OEt(2))(2)](BArf)-B-+(BArf = B(3,5-(CF3)(2)C6H3)(4)) to 1 in ether at -78 degrees C afforded the solvent complex trans-[(PiPr(3))(2)Pt(H)(OEt(2))]BArf (2) in 85% isolated yield. Complex 2 served as a precursor to monodentate halocarbon complexes of the type Pt(eta(1)-XR). The dichloromethane complex trans-[(PiPr(3))(2)Pt(H)(eta(1)-ClCH2Cl)]BArf (3) was isolated in 80% yield by the recrystallization of 2 from CH2Cl2/hexane. IR spectroscopy suggested the existence of dichloromethane binding which was confirmed by X-ray crystallography. The reaction of 2 or 3 with iodo- or bromobenzene led to the isolation of the haloarene complexes trans-[(PiPr(3))(2)Pt(H)(eta(1)-XPh)]BArf, where X = I (4, 87% yield) or Br (5, 60% yield). Both compounds were characterized spectroscopically and by X-ray crystallography. An unexpected steric interaction in 4, suggested by molecular mechanics calculations to be significant, was rationalized in terms of halide-to-metal pi bonding. The PhI complex 4 decomposed under harsh conditions to the bridging iodide compound trans-[(PiPr(3))(2)Pt(H)](2)(mu-I)}BArf (6) which was structurally characterized. The THF adduct [(PiPr(3))(2)Pt(H)(THF)]BArf (7), isolated in 78% yield and also characterized by X-ray crystallography, was formed when any of the compounds 2, 3, 4, or 5 was dissolved in THF. The CH2Cl2 complex 3 reacted with H-2 to form the dihydrogen complex tans-[(PiPr(3))(2)Pt(H)(eta(2)-H-2)]BArf which was characterized by NMR spectroscopy.
