A palladium-catalyzed Negishi cross-coupling reaction of ethyl bromodifluoroacetate with arylbromides or aryl triflates to construct C(sp2)–CF2 bonds is described. The reaction was conducted under mild reaction conditions, and no preparation of organozinc reagents is required. This is the first report encompassing the conversion of aryl triflates into products containing C–CF2 bonds. In addition,
Palladium-Catalyzed Difluoroalkylation of Aryl Boronic Acids: A New Method for the Synthesis of Aryldifluoromethylated Phosphonates and Carboxylic Acid Derivatives
The palladium‐catalyzed difluoroalkylation of arylboronicacids with bromodifluoromethylphosphonate, bromodifluoroacetate, and further derivatives has been developed. This method provides a facile and useful access to a series of functionalized difluoromethylated arenes (ArCF2PO(OEt)2, ArCF2CO2Et, and ArCF2CONR1R2) that have important applications in drug discovery and development. Preliminary mechanistic
已开发出溴化二氟甲基膦酸酯,溴化二氟乙酸酯和其他衍生物的钯催化的芳基硼酸二氟烷基化反应。该方法为在药物发现和开发中具有重要应用的一系列功能化的二氟甲基化芳烃(ArCF 2 PO(OEt)2,ArCF 2 CO 2 Et和ArCF 2 CONR 1 R 2)提供了便捷而有用的途径。初步的机理研究表明,单电子转移(SET)途径可能参与了催化循环。
