The synthesis of alkyl esters from readily available alkyl halides and chloroformates was achieved for the first time using a mild Ni-catalyzed reductive coupling protocol. Unactivated primary and secondary alkyl iodides as well as glycosyl, benzyl, and aminomethyl halides were successfully employed to yield products in moderate to excellent yields with high functional group tolerance.
使用温和的Ni催化还原偶联协议首次实现了从容易获得的烷基卤化物和氯甲酸酯合成烷基酯。未活化的伯和仲烷基碘化物以及糖基,苄基和氨基甲基卤化物已成功用于以中等到极好的收率生产具有高官能团耐受性的产品。
