  Regioselective Gold-Catalyzed Hydration of CF₃- and SF₅-alkynes

  摘要：

  The regioselective gold-catalyzed hydration of CF3- and SF5-alkynes is described. The corresponding trifluoromethylated and pentasulfanylated ketones are obtained in up to 91% yield as single regioisomers showcasing the use of CF3 and SF5 as highly efficient directing groups in this reaction. Notably, this transformation represents the first use of CF3- and SF5-alkynes in gold catalysis.

• Highly regio- and stereo-selective carbometallation reaction of fluorine-containing internal acetylenes with organocopper reagents

  The carbometallation reactions of fluoroalkylated internal alkynes with various organocopper reagents derived from organolithium, Grignard, and organozinc reagents were examined. All carbocupration reactions proceeded smoothly in a highly regio- and stereo-selective manner to give the corresponding vinylcopper intermediates. The intermediates reacted with H+ smoothly, leading to the trisubstituted

  考察了氟代烷基化内部炔烃与衍生自有机锂，格利雅（Grignard）和有机锌试剂的各种有机铜试剂的碳金属化反应。所有的碳吸收反应均以高度区域选择性和立体选择性的方式顺利进行，得到相应的乙烯基铜中间体。中间体与H +反应平稳地生成三取代烯烃，产率高至优异，而它们仅与严格限定的碳亲电试剂（如烯丙基，巴豆基，甲基烯丙基溴等）反应，这可能是由于吸电子氟代烷基的低反应性所致。用碘处理乙烯基铜导致相应的乙烯基碘的高收率，已成功用于铃木-宫浦和Sonogashira的交叉偶联反应。此外，碳键合和铃木-宫浦交叉偶联反应这两个关键反应实现了抗雌激素药泛美芬的第一个高度立体选择性的全合成。

  Two practical and complementary methods are reported for the synthesis of trifluoromethylated alkynes. The first one, a mix‐and‐stir process, is based on the oxidative trifluoromethylation of readily available and bench‐stable copper acetylides while the second one, which displays a broad substrate scope and has several advantages over existing procedures, is based on the oxidative copper‐catalyzed

  Treatment of various fluorinated internal alkynes with 10 mol% of RhCl3·H2O and 30 mol% of i-Pr2NEt in toluene at the reflux temperature for 18 h gave the corresponding trimerization products as an isomeric mixture in high yields. Cycloaddition using 1.0 equiv. of fluorinated alkynes and 2.0 equiv. of non-fluorinated alkynes under the same reaction conditions as in the trimerization led to mono- and

  Hydrosilylation reaction of various fluoroalkylated alkynes with Et3SiH in the presence of a catalytic amount of Co2(CO)8 was investigated. The hydrosilylation of the alkynes having fluoroalkyl and aryl groups took place smoothly with good regioselectivity (ca. 80:20). In sharp contrast, the reaction of the alkynes having a fluoroalkyl group and a benzyl-type substituent, or various propargyl alcohols gave the corresponding vinylsilanes in an excellent regio- and stereoselective manner. Treatment of the vinylsilanes with various aldehydes in the presence of Zn(OTf)2 and TBAF afforded the coupling products in good yields.

  在催化剂 Co2(CO)8 的存在下，研究了各种氟烷基炔烃与 Et3SiH 的氢硅化反应。具有氟烷基和芳基的炔烃顺利发生了氢硅烷化反应，且具有良好的区域选择性（约为 80:20）。与此形成鲜明对比的是，具有氟烷基和苄基取代基的炔烃或各种丙炔醇以极好的区域和立体选择性反应生成相应的乙烯基硅烷。在 Zn(OTf)2 和 TBAF 的存在下，用各种醛处理乙烯基硅烷，可以得到产率很高的偶联产物。
