  摘要：

  报道了通过结合苯酚的O-羧基二氟甲基化和随后的脱羧氟化来合成芳基三氟甲基醚（ArOCF 3）的新策略。该方案允许以中等至良好的产率容易地构建官能化的三氟甲氧基苯和三氟甲基硫醇化的芳烃（ArSCF 3）。而且，它利用可及的和便宜的试剂溴二氟乙酸钠和SelectFluor II，因此对于苯酚的O-三氟甲基化是实用的。制备植物生长调节剂氟草啶醇证明了该方法的潜在应用。

  日期：2020.10.5

  efficient palladium‐catalyzed chlorocarbonylation of aryl (pseudo)halides that gives access to a wide range of carboxylic acid derivatives has been developed. The use of butyryl chloride as a combined CO and Cl source eludes the need for toxic, gaseous carbon monoxide, thus facilitating the synthesis of high‐value products from readily available aryl (pseudo)halides. The combination of palladium(0), Xantphos
