1,1-Difluoroethylated aromatics are of great importance in medicinal chemistry and related fields. 1,1-Difluoroethyl chloride (CH3CF2Cl), a cheap and abundant industrial raw material, is viewed as an ideal 1,1-difluoroethylating reagent, but the direct introduction of the difluoroethyl (CF2CH3) group onto aromatic rings using CH3CF2Cl has not been successfully accomplished. Herein, we disclose a nickel-catalyzed
1,1-二氟乙基化芳烃在药物化学及相关领域具有重要意义。1,1-二氟乙基氯(CH 3 CF 2 Cl)是一种廉价且丰富的工业原料,被视为理想的1,1-二氟乙基化试剂,但将二氟乙基(CF 2 CH 3)基团直接引入芳烃使用 CH 3 CF 2 Cl 的环尚未成功完成。在此,我们公开了一种镍催化的芳基硼酸与 CH 3 CF 2 Cl 的 1,1-二氟乙基化反应,用于合成 (1,1-二氟乙基)芳烃。
