1,1-Difluoroethylated aromatics are of great importance in medicinal chemistry and related fields. 1,1-Difluoroethyl chloride (CHCFCl), a cheap and abundant industrial raw material, is viewed as an ideal 1,1-difluoroethylating reagent, but the direct introduction of the difluoroethyl (CFCH) group onto aromatic rings using CHCFCl has not been successfully accomplished. Herein, we disclose a nickel-catalyzed 1,1-difluoroethylation of arylboronic acids with CHCFCl for the synthesis of (1,1-difluoroethyl)arenes.
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。1,1-二氟氯乙烷（CHCFCl）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，但使用CHCFCl将二氟乙基（CFCH）基团直接引入芳环尚未成功实现。在此，我们报道了一种镍催化的芳基硼酸与CHCFCl的1,1-二氟乙基化反应，用于合成（1,1-二氟乙基）芳烃。
