Desulfonylative Iodination of Naphthalenesulfonyl Chlorides with Zinc Iodide or Potassium Iodide Catalyzed by Dichlorobis(benzonitrile)palladium(II) in the Presence of Lithium Chloride and Titanium(IV) Isopropoxide
Iodination of naphthalenesulfonyl chlorides accompanied by desulfonylation efficiently proceeded on treatment with either zinc iodide or potassium iodide using a catalyst system of /LiCl/Ti(OPr2)4.
