reaction of aryl thianthrenium salts to smoothly prepare various aryl sulfonyl fluorides using cheap Na2S2O4 as a convenient sulfonyl source in combination with N-fluorobenzenesulfonimide (NFSI) as an ideal fluorine source under mild reduction conditions. A one-pot synthesis of aryl sulfonyl fluorides starting from various arenes was established as well without the need for separating aryl thianthrenium
我们开发了一种高效的钯催化芳基噻蒽盐的氟磺酰化反应,以廉价的 Na 2 S 2 O 4作为方便的磺酰源,结合N-氟苯磺酰亚胺 (NFSI) 作为理想的氟源,在温和还原下顺利制备各种芳基磺酰氟状况。还建立了从各种芳烃开始的芳基磺酰氟的一锅法合成,而无需分离芳基噻蒽盐。该协议的实用性通过克级合成、衍生化反应和优异的产量得到证明。
