α-Fluorinated aryl esters pose a challenge in synthesis via O-arylation of α-fluorinated carboxylates owing to their low reactivities. This limitation has been addressed by combining a silver catalyst with aryl(trimethoxyphenyl)iodonium tosylates to access α-fluorinated aryl esters. We envision that the catalytic system involves high-valent aryl silver species generated via the oxidation of silver(I)
由于其低反应活性,α-氟化芳基酯在通过 α-氟化羧酸酯的O-芳基化合成中提出了挑战。通过将银催化剂与芳基(三甲氧基苯基)碘鎓甲苯磺酸盐组合以得到α-氟化芳基酯,解决了这一限制。我们设想催化系统涉及通过银(I)盐氧化产生的高价芳基银物质。本方法提供了各种α-氟化芳基酯(包括药物衍生物的氟化类似物)的合成方案。
