  Polyhedral and Spiro Platinum−Silyl Clusters Bearing Phosphine Ligands

  摘要：

  Treatment of [Pt(L-2)(eta(2)-C2H4)] (L-2 = dppe or (PPh3)(2)) with (H3SiSiMe2Bu)-Bu-1 at room temperature afforded the corresponding trigonal bipyramidal clusters [Pt-3(L-2)(3)(mu(3)-SiH)(2)]. In the case of L-2 = dppe, the octahedral cluster [Pt-4-(dppe)(4)(mu(4)-SiH)(2)] and the spiro-type cluster [Pt-4(dppe)(4)-(mu(4)-Si)] were also generated when the molar ratio of the zerovalent platinum complex to the disilane was increased.

  A hydrogen-bridged bis(silylene) complex, which can be viewed as a snapshot of a transition state for 1,3-hydrogen migration, was isolated, and its unprecedented WSi2H four-membered-ring structure with a short diagonal Si-Si distance was revealed by X-ray crystallography. NMR studies including determination of the W-Si, Si-Si, and Si-H coupling constants and theoretical calculations suggest that a novel multicenter bond is formed in the WSi2H system, in which the bridging hydrogen takes on a hydridic nature.
