the three-component reaction of arenediazonium tetrafluoroborates, Na2S2O5, and N-fluorobenzenesulfonimide (NFSI). The reaction proceeds through a radical tandem process, affording various arenesulfonyl fluorides 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。
