  Ni-Catalyzed Regioselective Hydrocarboxylation of Alkynes with CO₂ by Using Simple Alcohols as Proton Sources

  摘要：

  A mild and user-friendly Ni-catalyzed regioselective hydrocarboxylation of alkynes with CO2 (1 bar) is described. This protocol is characterized by a wide scope While obviating the need for sensitive organometallic, species and by an unprecedented regioselectivity pattern using simple alcohols as proton sources.

  The carbonylation of alkanes 1 under radical-reaction conditions was examined by using ethynyl triflone A as the unimolecular chain-transfer (UMCT) reagent. Good to moderate yields of ethynyl ketones 2 were prepared by means of this three-component coupling reaction. Higher CO pressures as well as lower concentrations of triflone A improved the efficiency of the reaction over the direct addition, the

  使用乙炔基三氟甲酮A作为单分子链转移（UMCT）试剂，检查了自由基反应条件下烷烃1的羰基化作用。通过这种三组分偶联反应，制备了乙炔基酮2的良好至中等的产率。与直接添加相比，较高的CO压力和较低的三氟甲酮A浓度提高了反应效率，后者导致烷基化乙炔3。与与A的反应相反，环己烷（1a）与烯丙基三酮B的反应。（＝ 2-亚甲基-3-[[（三氟甲基）磺酰基]丙酸乙酯）在CO存在下得到羰基化产物的混合物，包括由环己烷，CO和烯丙基三氟乙烯乙的两个分子各自形成的8a。

  Two sets of conditions have been developed for a base-mediated, transition-metal-free alkynylation of aryl chlorides that proceeds via benzyne intermediates. The first set of conditions Involves the use of TMPLI base in a pentane/THF mixture at 25 degrees C. The second set Involves use of a metal alkoxide base in dioxane at elevated temperature. Reasonable functional group tolerance has been observed. Fluoro, trifluoromethyl, silyl, cyano, and alcohol functionalities are compatible with the reaction conditions.

  Getting a fix: The copper‐catalyzed hydrocarboxylation of alkynes using carbon dioxide in the presence of a hydrosilane, which serves as a reducing agent, has been developed (see scheme). Copper fluorides bearing N‐heterocyclic carbene ligands such as IMes and Cl2IPr show high catalytic activities.
