Convenient One-Pot Synthesis of Sulfonamides and Sulfonyl Azides from Thiols Using N-Chlorosuccinimide

[摘要]：A convenient synthesis of sulfonamides and 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.
