A novel Ni(0) -catalyzed carboxylation of aryl tosylates with carbon dioxide has been achieved under moderate temperatures and atmospheric pressure. In this procedure, the active Ni(0) species is generated in situ by simply mixing the Ni(0) precatalyst [NiBr2 (bipy)] with an excess of manganese metal. This approach requires neither a glove-box nor the tedious preparation of sophisticated intermediate organometallic derivatives. This mild, convenient, and user-friendly process is successfully applied to the valorization of carbon dioxide and the synthesis of versatile reactants with broad tolerance of substituents.
在温和温度和大气压下实现了一种新型的镍（0）催化芳基甲苯磺酸酯与二氧化碳的羧化反应。在此过程中，通过简单地将镍（0）预催化剂[NiBr2（联吡啶）]与过量的锰金属混合，原位生成活性镍（0）物种。该方法既不需要手套箱，也不需要繁琐地制备复杂的中间体有机金属衍生物。这种温和、便捷且用户友好的过程已成功应用于二氧化碳的增值利用以及对取代基具有广泛耐受性的通用反应物的合成。
