A mild and efficient synthesis of various aryl sulfonyl fluorides from diaryliodonium salts under organophotocatalysis a radical sulfur dioxide insertion and fluorination strategy is presented. Diaryliodonium salts are used as aryl radical precursors, the 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO) as a sulfonyl source and cheap KHF as a desirable fluorine source, respectively. Notably, the electronic properties of substituents on the aromatic rings in diaryliodonium salts have a significant influence on the reaction yields.
报道了一种在有机光催化下由二芳基碘鎓盐温和高效地合成各种芳基磺酰氟的方法——一种自由基二氧化硫插入和氟化策略。二芳基碘鎓盐分别用作芳基自由基前体，1,4-二氮杂双环[2.2.2]辛烷双（二氧化硫）加合物（DABSO）用作磺酰基源，廉价的KHF用作理想的氟源。值得注意的是，二芳基碘鎓盐中芳环上取代基的电子性质对反应产率有显著影响。
