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。
