A convenient synthesis of sulfonamides and sulfonyl azides from thiols is described. In situ preparation of sulfonyl chlorides from thiols was accomplished by oxidation with chloramine‐T (=N‐chlorotosylamide=N‐chloro‐4‐methylbenzenesulfonamide), tetrabutylammonium chloride (Bu4NCl), and H2O. The sulfonyl chlorides were then further allowed to react with excess amine or NaN3 in the same pot.
描述了由硫醇方便地合成磺酰胺和磺酰叠氮化物。通过用氯胺-T(= N-氯代甲苯磺酰胺= N-氯--4-甲基苯磺酰胺),四丁基氯化铵(Bu 4 NCl)和H 2 O氧化,可以完成从硫醇中磺酰氯的原位制备。在同一锅中与过量的胺或NaN 3反应。
