A one-pot procedure for the synthesis of arenesulfonyl fluorides from arylamine is developed with K2S2O5 and N-fluorobenzenesulfonimide (NFSI) as the sulfur dioxide surrogate and fluorine source, respectively. This method realizes the direct introduction of sulfonyl fluoride groups into arenes from abundant arylamines under transition-metal-free catalysis conditions, and features its mild and practical
采用 K 2 S 2 O 5和 N-氟苯磺酰亚胺 (NFSI) 分别作为二氧化硫替代物和氟源,开发了一种从芳胺合成芳基磺酰氟的一锅法。该方法实现了在无过渡金属催化条件下从丰富的芳胺中直接将磺酰氟基团引入芳烃中,具有条件温和实用、官能团耐受性好的特点。
