描述了钯催化的有机碘化物的氟磺酰乙烯基化反应。催化 Pd(OAc)2 与化学计量三氟乙酸银 (I) 能够实现(杂)芳基或烯基碘与乙烯磺酰氟之间的偶联过程 (ESF, 1)。该方法已成功合成 88 种原本难以获得的化合物,产率高达 99%,其中包括前所未有的 2-杂芳基乙烯磺酰氟和 1,3-二烯基磺酰氟。催化 Pd(OAc)2 与化学计量三氟乙酸银 (I) 能够实现(杂)芳基或烯基碘与乙烯磺酰氟之间的偶联过程。该方法已成功合成 88 种原本难以获得的化合物,产率高达 99%,其中包括前所未有的 2-杂芳基乙烯磺酰氟和 1,3-二烯基磺酰氟。
A palladium-catalyzed fluorosulfonylvinylation reaction of organic iodides is described. Catalytic Pd(OAc)2 with stoichiometric silver(I) trifluoroacetate enables the coupling process between an (hetero)aryl or alkenyl iodide and ethenesulfonyl fluoride (ESF, 1). The method is demonstrated in the successful syntheses of eighty-eight otherwise difficult to access compounds in up to 99% yields, including the unprecedented 2-heteroarylethenesulfonyl fluorides, and 1,3-dienylsulfonyl fluorides.
