  Platinum-Catalyzed Nucleophilic Addition of Vinylsilanes at the β-Position

  摘要：

  In the presence of catalytic amounts of PtCl(2) and metal iodides, beta-substituted vinylsilanes reacted with aldehydes at the beta-position to give allyl silyl ethers. The Pt-catalyzed addition to aromatic aldehydes proceeded efficiently in the presence of Lil. The combined use of PtCl(2) and Mnl(2) was found to be effective in addition to aliphatic aldehydes.

  日期：1993.8

  Triethylborane induced radical addition of various organosilanes (R3SiH) to acetylenes has been studied. Among them, tris(trimethylsilyl)silane (TTMSS) proved to be the best reagent for the hydrosilylation of acetylenic compounds in terms of yield and stereoselectivity. For instance, reaction of 1-dodecyne with TTMSS at room temperature for 3 h under Et3B catalyst provided (Z)-1-tris(trimethylsilyl)silyl-1-dodecene

  已经研究了三乙基硼烷引发的各种有机硅烷 (R3SiH) 与乙炔的自由基加成。其中，就产率和立体选择性而言，三（三甲基甲硅烷基）硅烷（TTMSS）被证明是炔类化合物氢化硅烷化的最佳试剂。例如，1-十二炔与 TTMSS 在室温下在 Et3B 催化剂下反应 3 小时，选择性地提供了 (Z)-1-三(三甲基甲硅烷基)甲硅烷基-1-十二烯，产率为 98%。已经研究了用 TTMSS-Et3B 或 n-Bu3SnH-Et3B 还原烯基碘的立体化学过程。在室温下用 TTMSS-Et3B 处理 1-二甲基苯基甲硅烷基-2-碘-1-十二烯，选择性地提供 (Z)-1-二甲基苯基甲硅烷基-1-十二烯 (Z/E > 30/1)。另一方面，用 n-Bu3SnH-Et3B 处理只得到 (E)-1-二甲基苯基甲硅烷基-1-十二烯。

  R3SiMgMe and MnCl2 are disclosed. (1) The manganese species reacted with terminal acetylenes to give 1,2-disilylated 1-alkenes. Mono- and bis(trimethylsilyl) acetylenes gave tri- and tetrasilylated ethenes, respectively, in good yields. Highly strained tetrakis(trimethylsilyl) ethene has now become easily accessible by this technique. (2) The reaction of alkenyl halides, alkenyl sulfides, and enol phosphates

  由3个当量衍生的试剂介导的合成上有用的反应。R 3 SiMgMe和MnCl 2的合成被披露。（1）锰与末端乙炔反应生成1,2-二甲硅烷基化的1-烯烃。单和双（三甲基甲硅烷基）乙炔分别以高收率得到三和四甲硅烷基化的乙烯。现在，通过这种技术可以轻松获得高应变四（三甲基甲硅烷基）乙烯。（2）链烯基卤化物，链烯基硫化物和烯醇磷酸盐与标题试剂的反应提供了高产率的乙烯基硅烷。该方法也适用于由烯丙基硫化物和醚合成烯丙基硅烷。（3）用锰试剂处理1，3-二烯提供了甲硅烷基化的烯丙基锰化合物，其以高的区域选择性加到羰基部分上。

  The reaction of alkenyl halides, alkenyl sulfides, and enol phosphates with (R3Si)3MnMgMe provides vinylsilanes in good yields. The method is also applicable to the allylsilane synthesis from allylic sulfides and ethers.

  日期：1991.8

  The reduction of alkenyl halides with tributyltin hydride in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium has been studied. Alkenyl iodides reacted easily with tributyltin hydride at 25°C to give the corresponding hydrocarbons stereoselectively. However, the reaction of alkenyl bromides were sluggish at 25°C and needed heating at 75°C to complete.

  Silicon-directed stereoselectivesyn addition of hydroxy group to olefinic double bond occurs intramolecularly in an acid-catalyzed cyclization of vinylsilanes bearing hydroxy group. Thus 5-dimethylphenylsilyl-4-penten-1-ol is smoothly cyclized to 2-(dimethylphenylsilyl)methyltetrahydrofuran upon the treatment of a catalytic amount ofp-toluenesulfonic acid (TsOH) or TiCl4.

  硅定向立体顺式加成羟基基团与烯属双键在乙烯基硅烷轴承羟基的酸催化环化分子内发生。因此，在催化量的对甲苯磺酸（TsOH）或TiCl 4处理后，将5-二甲基苯基甲硅烷基-4-戊烯-1-醇平滑地环化为2-（二甲基苯基甲硅烷基）甲基四氢呋喃。
