  Cross-Coupling of Alkynylsilanols with Aryl Halides Promoted by Potassium Trimethylsilanolate

  摘要：

  The palladium-catalyzed cross-coupling of aliphatic alkynylsilanols with aryl iodides has been demonstrated with potassium trimethylsilanolate as the coupling promoter and copper(I) iodide as a cocatalyst. The cross-coupling proceeds at room temperature in good to excellent yield with a range of aryl iodides. A comparison of the reactivity of alkynylsilanols, trimethylsilylalkynes, and terminal alkynes under fluoride and fluoride-free conditions was per-formed to elucidate the role of silicon in the Sonogashira reaction.

  Dual photoredox transition-metal catalysis has recently emerged as a powerful tool for making synthetically challenging carbon–carbon bonds under milder reaction conditions. Herein, we report on the visible-light-mediated controlled generation of low-valent cobalt catalyst without the need for a metallic reductant. It enabled C–C bond formation via ene-yne coupling at room temperature. The generality

  最近，双重光氧化还原过渡金属催化已成为一种在较温和的反应条件下制备具有挑战性的碳-碳键的有力工具。在本文中，我们报道了在不需要金属还原剂的情况下可见光介导的低价钴催化剂的受控生成。它可以在室温下通过ene-yne偶联形成C–C键。这种双重催化的普遍性通过容纳多个官能团的可观分子多样性的创造得到证明。

  The Sonogashira cross-coupling reaction between aryl halides and terminal alkynes was carried out smoothly in water over a thermoregulated ligand–palladium catalyst under copper-free conditions, resulting in good to excellent yields. The Sonogashira reaction was sensitive to the electronic nature of the substituents on the aryl halides. Aryl halides with an electron-withdrawing group showed higher

  芳基卤化物和末端炔烃之间的 Sonogashira 交叉偶联反应在无铜条件下在温度调节的配体 - 钯催化剂上在水中顺利进行，产生了良好的产率。Sonogashira 反应对芳基卤化物上的取代基的电子性质很敏感。具有吸电子基团的芳基卤化物比具有给电子基团的芳基卤化物表现出更高的反应性。特别是, 该协议可应用于涉及 trans-cyclohexyltolans 的液晶合成。产物可以通过滗析很容易地从反应体系中分离出来，催化剂在水中回收，直接用于下一次运行。

  Cu2O/PPh3/TBAB (n-Bu4NBr) system for the cross-coupling reactions of aryl and heteroaryl halides with terminal alkynes has been developed. Four types of Cu2O, including bulky Cu2O, cubic Cu2O nanoparticles, octahedral Cu2O nanoparticles, and spherical Cu2O nanoparticles, were examined, and the octahedral Cu2O nanoparticles were found to be the most effective catalyst for the reaction. In the presence of the octahedral

  已开发出一种有效且可重复使用的Cu 2 O / PPh 3 / TBAB（n -Bu 4 NBr）系统，用于芳基卤化物和杂芳基卤化物与末端炔烃的交叉偶联反应。检查了四种类型的Cu 2 O，包括大块Cu 2 O，立方Cu 2 O纳米颗粒，八面体Cu 2 O纳米颗粒和球形Cu 2 O纳米颗粒，发现八面体Cu 2 O纳米颗粒是最有效的催化剂反应。在存在八面体Cu 2 O纳米粒子的情况下，PPh 3和TBAB，各种芳基和杂芳基卤化物与炔烃（包括炔醇）的反应均以中等至良好的收率顺利进行。值得注意的是，Cu 2 O / PPh 3 / TBAB系统可以回收并重复使用多次，而不会损失任何活性。
