We report herein a general and practical copper-catalyzed fluorosulfonylation reaction of a wide range of abundant arenediazonium salts to smoothly prepare various arenesulfonylfluorides using the 1,4-diazabicyclo[2.2.2]octane-bis(sulfur dioxide) adduct as a convenient sulfonyl source in combination with KHF2 as an ideal fluorine source and without the need for additional oxidants. Interestingly,
the three-component reaction of arenediazonium tetrafluoroborates, Na2S2O5, and N-fluorobenzenesulfonimide (NFSI). The reaction proceeds through a radical tandem process, affording various arenesulfonylfluorides in moderate to high yields. This protocol not only provides a complement to the previous fluorosulfonylation reactions, but also extends the applications of Sandmeyer reaction.
通过四氟硼酸壬二唑鎓,Na 2 S 2 O 5和N-氟苯磺酰亚胺(NFSI)的三组分反应,实现了无过渡金属的Sandmeyer型氟磺酰化反应。该反应通过自由基串联过程进行,以中等至高产率提供各种芳烃磺酰氟。该方案不仅为以前的氟磺酰化反应提供了补充,而且扩展了桑德迈尔反应的应用。

meta-isomers commence with the appropriate bromo-substituted benzenesulfonylchlorides, and the ortho-isomer is prepared from benzenesulfonyl fluoride. The para- and meta-substituted boronic acids undergo efficient Sukuki-Miyaura coupling reactions with a range of aryl halides. We also report an efficient Rh(I)-catalyzed conjugate addition reaction using the para-substituted boronic acid.

A copper-free Sandmeyer-type fluorosulfonylation reaction is reported. Utilizing Na2S2O5 and Selectfluor as the sulfur dioxide and fluorine sources, respectively, aryldiazonium salts were transformed into sulfonyl fluorides. The one-pot direct synthesis of sulfonyl fluorides from aromatic amines was also realized via in situ diazotization. The practicality of this method was demonstrated by the broad
据报道,无铜Sandmeyer型氟磺酰化反应。利用Na 2 S 2 O 5和Selectfluor分别作为二氧化硫和氟源,将芳基重氮盐转化为磺酰氟。还可以通过原位重氮化实现一锅直接由芳族胺合成磺酰氟的方法。天然产品和药物的广泛官能团耐受性,克级合成以及后期的氟磺酰化证明了该方法的实用性。
