The nickel-catalyzed three-component reductive carbonylation of alkylhalides, aryl halides, and ethyl chloroformate is described. The use of ethyl chloroformate as a safe and readily available source of CO provides an efficient and practical alternative for the synthesis of aryl-alkyl ketones.
描述了烷基卤化物、芳基卤化物和氯甲酸乙酯的镍催化三组分还原羰基化。使用氯甲酸乙酯作为一种安全且容易获得的 CO 来源,为芳基烷基酮的合成提供了一种有效且实用的替代方案。
Nickel/Photoredox-Catalyzed Carbonylative Cross-Electrophile Coupling of Organohalides and Carboxylic Acid Esters with Phenyl Formate
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.
