  Reaction of a Symmetrical Diplatinum Complex Containing Bridging μ-η²-H−SiH(IMP) Ligands (IMP = 2-Isopropyl-6-methylphenyl) with PMe₂Ph. Formation and Characterization of {(PhMe₂P)₂Pt[μ-SiH(IMP)]}₂

  摘要：

  A dinuclear Pt-Si complex containing bridging eta(2)-H-SiH(IMP) (IMP = 2-isopropyl-6-methylphenyl) ligands, {(Ph3P)Pt[mu-eta(2)-H-SiH(IMP)]}(2) (1) has been synthesized and characterized;by NMR and X-ray crystallography. A 3c-2e nonclassical interaction. between Pt ... H ... Si is supported by spectroscopic and crystallographic data. Complex 1 reacts with the more basic and less hindered phosphine PMe2Ph to afford a different dinuclear Pt-Si complex with loss of H-2, {(PhMe2P)(2)Pt[mu-SiH(IMP)]}(2) (2). Complex 2 was characterized by multinuclear NMR spectroscopy.

  Reaction of(IMP)SiH3 with (PhnMe3-nP)(2)PtMe2 at 50 degreesC provided the dinuclear complexes trans-[(PhnMe3-nP)(2)Pt(mu -SiHAr)](2) [Ar = 2-isopropyl-6-methylphenyl (IMP)]. These complexes were characterized by multinuclear NMR and IR spectroscopy and X-ray crystallography. The Si-29 NMR chemical shift for PhMe2P)(2)Pt[mu -SiH(IMP]}(2) appears at unusually high field (-134 ppm) for complexes containing bridging silylene moieties. The X-ray structures of these complexes reveal acute Si-Pt-Si and obtuse Pt-Si-Pt angles. In solution, (Ph2MeP)(2)Pt[mu -SiH(IMP)]}(2) undergoes dissociation of PMePh2 down to - 90 degreesC.
