  The CuI-catalyzed carboxylation of terminal alkynes with CO2 and alkyl halides using ethylene carbonate as the solvent under mild conditions was studied. DFT calculations reveal that the energy barrier for CO2 insertion into the sp-hybridized Cu–C bond could be reduced by employing ethylene carbonate as the solvent. Notably, the procedure was conducted under ambient CO2 pressure without any external ligands. A broad range of substrates with electron-withdrawing groups or electron-donating groups gave the corresponding products in reasonable yields.

  研究了在温和条件下，使用乙烯碳酸酯作为溶剂，通过CO2和烷基卤化物对末端炔烃进行CuI催化的羧化反应。DFT计算表明，使用乙烯碳酸酯作为溶剂能够降低CO2插入sp杂化Cu–C键的能量障碍。值得注意的是，整个过程是在常温常压的CO2条件下进行的，且没有使用任何外部配体。多种具有电子吸引基团或电子捐赠基团的底物都能以合理的产率得到相应的产物。

  An ionic liquid containing copper(I) proved to be an effective homogeneous catalyst for the carboxylation of terminal alkynes with ambient CO2. This developed procedure needs no external ligands and terminal alkynes with various groups proceeded smoothly at atmospheric CO2 pressure and room temperature. Interestingly, the ILs containing copper(I) in both the anion and the cation showed much higher

  含有铜（I）的离子液体被证明是用于末端炔烃与环境CO 2羧化的有效均相催化剂。该开发的方法不需要外部配体和带有各种基团的末端炔烃，这些炔基在大气CO 2压力和室温下可顺利进行。有趣的是，与仅以卤化高硼酸盐形式（即阴离子中的铜（I））掺入铜（I）的对应物相比，在阴离子和阳离子中均包含铜（I）的ILs表现出更高的活性。特别地，还通过NMR技术证实了末端炔烃被离子液体的活化作用。

  Activated carbon supported CuBr was found to be an efficient catalyst for the carboxylation of terminal alkynes under atmospheric pressure of CO2 using ethylene carbonate as solvent at 80 degrees C for only 2 h, as verified with (CO2)-C-13. Various terminal alkynes could react smoothly with CO2 and organic halides under the reaction conditions to afford the corresponding carboxylic esters. In addition, the catalyst can be easily recovered and reused at least five times without significant loss of activity.

  We report here two cluster-based MOFs I and II as excellent heterogeneous catalysts in the carboxylation reactions of CO₂ and terminal alkynes under 1 atm and mild conditions. This is the first time for MOFs materials to catalyze this type of reactions.
