  摘要：

  The first donor-stabilized [bis(silylene)]ruthenium compex, Cp(Ph3P)Ru(SiMe2---O(Me)---SiMe2), has been synthesized by the thermal reaction of CpRu(Pph3)2Me with HMe2SiSiMe2OMe. The X-ray crystal structure analysis of this complex revealed its distorted-piano-stool structure, containing a RuSi2O four-membered chelate ring with two short Ru-Si bonds and two long Si-O bonds.

  Ruκ²(Si,Si)-xantsil}(CO)(η⁶-C₆H₅CH₃) (1) was found to be a catalyst for oligomerization–deoligomerization of HSiMe₂SiMe₃ to give H(SiMe₂)_nMe (n = 1–8 at 90 °C for 2 days). Treatment of 1 with HSiMe₂SiMe₂OR (R = Me, t-Bu) led to quantitative formation of Ruκ³(O,Si,Si)-xantsil}(CO)(H)(SiMe₂•••O(R)•••SiMe₂)} (R = Me (2a), t-Bu (2b)), which also worked as a catalyst for oligomerization–deoligomerization of HSiMe₂SiMe₃. Based on these experimental results, a mechanism involving silyl(silylene) intermediates was proposed for the oligomerization–deoligomerization of HSiMe₂SiMe₃. Complex 2a reacted with MeOH in toluene-d₈ to give Ruκ²(Si,Si)-xantsil}(CO)(η⁶-toluene-d₈) and Me₂Si(OMe)₂ with evolution of H₂. Under a CO atmosphere, 2a was smoothly converted to its CO adduct Ruκ²(Si,Si)-xantsil}(CO)₂(H)(SiMe₂•••O(Me)•••SiMe₂)} (3).Key words: silylene complex, ruthenium, polysilane, dehydrogenative coupling, oligomerization.

  已发现 Ruκ²(Si,Si)-xantsil}(CO)(η⁶-C₆H₅CH₃) (1) 是 HSiMe₂SiMe₃ 的寡聚-去聚合催化剂，在90°C处理2天后生成 H(SiMe₂)_nMe (n = 1–8)。将1与HSiMe₂SiMe₂OR (R = Me, t-Bu) 反应，可定量生成 Ruκ³(O,Si,Si)-xantsil}(CO)(H)(SiMe₂•••O(R)•••SiMe₂)} (R = Me (2a), t-Bu (2b))，也可作为 HSiMe₂SiMe₃ 的寡聚-去聚合催化剂。基于这些实验结果，提出了涉及硅烷(硅烯)中间体的寡聚-去聚合机理。在甲苯-d₈中，2a 与 MeOH 反应生成 Ruκ²(Si,Si)-xantsil}(CO)(η⁶-甲苯-d₈) 和 Me₂Si(OMe)₂，伴随释放 H₂。在 CO 气氛下，2a 顺利转化为其 CO 加合物 Ruκ²(Si,Si)-xantsil}(CO)₂(H)(SiMe₂•••O(Me)•••SiMe₂)} (3)。关键词：硅烯配合物、钌、聚硅烷、脱氢偶联、寡聚合。
