A photoinduced nickel-catalyzed reductive carbonylative coupling from organohalides and N-(acyloxy)phthalimide esters with phenyl formate as the carbonyl source has been developed. This reaction could perform smoothly under mild conditions, and a series of aryl–alkyl and alkyl–alkyl unsymmetrical ketones were produced without the need of stoichiometric metal reductants. Mechanistic studies indicate
开发了一种以甲酸苯酯为羰基源的有机卤化物和N- (酰氧基)邻苯二甲酰亚胺酯的光诱导镍催化还原羰基化偶联反应。该反应在温和条件下顺利进行,无需化学计量的金属还原剂即可生成一系列芳基-烷基和烷基-烷基不对称酮。机理研究表明,该反应是由 Ni(I)-羰基物质的自由基捕获和随后的快速羰基插入引发的。
