A convenient synthesis of sulfonamidesand sulfonyl azides from thiols is described. In situ preparation of sulfonyl chlorides from thiols is accomplished by oxidation with N-chlorosuccinimide (NCS), tetrabutylammonium chloride, and water. The sulfonyl chlorides are then further allowed to react with excess amine or sodium azide in the same reaction vessel.
描述了从硫醇中方便地合成磺酰胺和磺酰叠氮化物。从硫醇原位制备磺酰氯是通过用 N-氯琥珀酰亚胺 (NCS)、四丁基氯化铵和水氧化来完成的。然后使磺酰氯在同一反应容器中进一步与过量的胺或叠氮化钠反应。
