  Chemistry of silyl thioketones. Part 10. Synthesis and reactivity of α-silyl vinyl sulfides

  摘要：

  Aliphatic silyl thioketones containing an alpha-hydrogen atom undergo enethiolization to Z-alpha-silyl enethiols 2. Compounds 2 react with a variety of halides R(3)X to give open-chain alpha-silyl vinyl sulfides 3. Protiodesilylation of 3 was achieved upon treatment with fluoride ion to give vinyl sulfides 4. Reaction of 3 with Grignard reagents, in the presence of an appropriate nickel catalyst, results in a series of vinylsilanes 5 with a specific geometry.

• Stereoconservative Formation and Reactivity of α-Chalcogen-Functionalized Vinyllithium Compounds from α-Bromo-vinylic Chalcogenides

  日期：1997.5

  Bromine/lithium exchange was performed upon treatment of α-bromo-vinylic chalcogenides with butyllithium in hexane at room temperature to provide α-chalcogen-vinyllithium intermediates quantitatively. Addition of electrophiles to the lithiated compounds gave the corresponding functionalized vinylic chalcogenides in good yields with retention of configuration.

  在室温下，将α-溴代乙烯类硫属化合物与正丁基锂在己烷中反应，进行溴锂交换，以定量提供α-硫属元素-乙烯基锂中间体。向锂化的化合物中加入亲电子试剂，可得到相应功能化的乙烯基硫属化合物，收率良好，并保持构型不变。
• Evaluation of C-trialkylsilyl enol and thioenol ethers as intermediates in the synthesis of acylsilanes

  C-silyl enol ethers or thioenol ethers have been prepared by a Peterson reaction, as intermediates for acylsilane synthesis. Bis(trialkylsilyl)(methoxy)- or -(methylsulfanyl)methanes bearing identical or different trialkylsilyl groups were used as starting materials in order to assess the selectivity of the Peterson elimination step. A good selectivity was observed only with ethers bearing the TMS

  通过Peterson反应已经制备了C-甲硅烷基烯醇醚或硫烯醇醚，作为酰基硅烷合成的中间体。为了评估彼得森消除步骤的选择性，将带有相同或不同三烷基甲硅烷基的双（三烷基甲硅烷基）（甲氧基）-或-（甲基硫烷基）甲烷用作起始原料。仅用带有TMS和TBDMS基团的醚观察到良好的选择性。然而，由于难以以正确的产率获得这些试剂，因此没有实际的兴趣来使用这些试剂。事实证明，双（三甲基甲硅烷基）（甲基硫烷基）甲烷是制备C-甲硅烷基硫烯醇醚的良好试剂，C-甲硅烷基硫烯醇醚在传统的酸性条件下可以水解，从而以合理的总收率得到酰基硅烷。该方便的过程扩展到双（酰基硅烷）的合成。

  日期：1997.6

  Cyclic and open chain a-silyl vinyl sulfides, obtained from thioacylsilanes, react with acid chlorides in the presence of Lewis acid to give thioannulated cyclopentenones and thiofunctionalized enones. The effect of the substituents at silicon on these reactions has been investigated. (C) 1997 Elsevier Science Ltd.
