  CO-Induced Reductive Elimination of P(t-Bu)₂H from the Platinum(II) Dinuclear Derivative Pt₂[μ-P(t-Bu)₂]₂(H)₂[P(t-Bu)₂H]₂, Affording Mononuclear Platinum(0) or Triangulo Triplatinum(I,I,II) Derivatives

  摘要：

  Carbon monoxide (1 atm) quantitatively converts the Pt(II) dinuclear derivative Pt-2[mu-P(t-Bu)(2)](2)(H)(2)[P(t-Bu)(2)H](2) (1) into the new (Pt2PtII)-Pt-I triangulo cluster Pt-3[mu-P(t-Bu)(2)](3)(H)(CO)(2) (2). The 44e(-) species 2 was characterized by IR and multinuclear NMR spectroscopy and by a single-crystal X-ray diffraction study. Complex 2 is formed through the slow CO-induced reductive elimination of P(t-Bu)(2)H from 1, affording the intermediate mononuclear Pt(0) carbonyl derivative Pt[P(t-Bu)(2)H](2)(CO)(2) (4), which equilibrates with the carbonyl-bridged triangulo derivative Pt-3[P(t-Bu)(2)H](3)(mu-CO)(3) (5); these are the main products under high pressures of CO. Two alternative mechanisms were examined for the subsequent formation of complex 2, the first being the rapid condensation of complex 4 with unreacted 1 while the second assumes 5 as the direct precursor of 2. Although the first mechanism cannot be conclusively rejected, the second seems the most appropriate, since under high pressures of CO/H-2 complex 2 was shown to equilibrate with 5. In the presence of an excess of other phosphines, the carbonylation of 1 yields quantitatively the mononuclear monocarbonyl derivatives Pt(PR(3))(3)(CO) (R(3) = Ph(3), Et(3), t-Bu(2)H).

  Synthesis, molecular and electronic structure of the first homoleptic complex of platinum with a secondary phosphine

  摘要：

  The reaction of CpPt(eta(3)-C3H5) with (PBu2H)-H-t in acetone gives the Pt(0) mononuclear derivative Pt((PBu2H)-H-t)(3) (1). As demonstrated by variable temperature P-31{H-1} NMR spectra, complex 1 dissociates one of the phosphines in toluene solution affording the 14e(-)Pt((PBu2H)-H-t)(2). The crystal and molecular structure of 1 was solved by X-ray diffraction which reveals a trigonal planar disposition of the phosphine molecules (C24H57P3Pt: hexagonal, space group P6(3)/m, a=b=10.4150(11), c=16.263(3) Angstrom, Z=2). The P-H hydrogen atoms were located in the Fourier map and were found to lie in the coordination plane, with the t-butyl substituents in an eclipsed configuration. Ab initio and molecular dynamics calculations essentially confirm the structure obtained by X-ray diffraction. Ar. agostic Pt-H-P interaction was excluded and the geometry was explained in terms of steric interactions. (C) 1997 Elsevier Science S.A.
