  AlCl₃-Catalyzed Hydrosilylation of Alkynes with Hydropolysilanes

  摘要：

  AlCl3 catalyzes addition reactions of hydrooliuosilanes (H(SiMe2)(n) R; n = 2-4, R = H, Me, Ph) with 1-decyne and other alkynes under mild conditions. In most reactions the Si Si bonds remain intact to form anticipated products in fair to excellent yields, although Si-Ph bonds appear to be cleaved partially under the conditions. Arylethynes tend to form abnormal products due to Si-Si bond scission, but at a low temperature, the addition reaction proceeds normally. The reaction of 1,2-dihydrotetramethyldisilane with 1-decyne furnishes 1,2-didecenyldisilane, 1,3-didecenyltrisilane, and other byproducts at 0 degrees C, while the reaction run at a lower temperature proceeds cleanly. 1,3-Dihydrohexamethyltrisilane reacts more cleanly even at 0 degrees C. The reaction of pentamethyldisilane with 1,6-heptadiyne proceeds in a different direction, leading to cyclization. 1,7-Octadiyne reacts with 1,3-dihydrohexamethyltrisilane to give a polymeric material. The reaction of 1,2,3-trihydropentamethyltrisilane or poly(phenylsilylene) with 1-dectyne proceeds cleanly without perceptible Si-Si bond cleavage.

  Dimeyhtylsilylene generated by photolysis of dodecamethylcyclohexasilane inserts sequentially into Si—H and Si—OR bonds of monosilanes to give high yields of the corresponding unsymmetrical di-, tri- and tetrasilanes.

  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。

  Ru(xantsil)(CO)(η6-C6H5CH3) (1) was found to be a catalyst for the oligomerization/deoligomerization of HSiMe2SiMe3 to give H(SiMe2)nMe (n=1–8). A possible mechanism involving a silyl(silylene) intermediate was strongly supported by the isolation of its stabilized form, i.e., alkoxy-bridged bis(silylene) complex which was characterized by X-ray crystal structure analysis.
