ZrCl4/NaI and ZrOCl2 · 8H2O/NaI as effective systems for reductive coupling of sulfonyl chlorides and chemoselective deoxygenation of sulfoxides

摘要

Zirconium tetrachloride/sodium iodide (ZrCU/Nal) and ZrOCl2 · 8HiO/NaI conduct effective reductive coupling of sulfonyl chlorides to their corresponding disulfides and chemoselective reduction of sulfoxides to their fhioethers in high yields.
