conversion of aryl iodide to aryl sulfonyl fluorides using DABSO and Selectfluor has been developed generating aryl sulfonyl fluorides in good to excellent yields. The reaction results in the generation of electronically and sterically diverse sulfonyl fluorides. Additionally, sulfonyl fluorides can be converted to aryl sulfonamides and sulfonic esters using Cs2CO3 under mild conditions.
已开发出使用DABSO和Selectfluor一锅Pd催化的芳基碘化物向芳基磺酰氟的转化,生成芳基磺酰氟的产率非常好。该反应导致产生电子和空间上不同的磺酰氟。另外,可以在温和的条件下使用Cs 2 CO 3将磺酰氟转化为芳基磺酰胺和磺酸酯。

Sulfonyl fluorides are useful motifs for a wide range of applications in organic synthesis including sulfur (VI) fluoride exchange-based “click chemistry.” Herein, a visible-light-mediated synthesis of sulfonyl fluoridesfrom arylazo sulfones is described. In the present study, K2S2O5 and N-fluorobenzenesulfonimide (NFSI) were used as the sulfonyl source and fluorinating agent, respectively, for v
磺酰氟是有机合成中广泛应用的有用基序,包括基于硫 (VI) 氟化物交换的“点击化学”。本文描述了一种由芳基砜合成磺酰氟的可见光介导合成方法。在本研究中,K 2 S 2 O 5和N-氟苯磺酰亚胺 (NFSI) 分别用作磺酰源和氟化剂,用于可见光介导的芳基砜的氟磺酰化,制备 60-85% 的各种磺酰氟。屈服。该协议是一种合成方法,可在室温下提供有用的磺酰氟结构。
