rmaceutical/Chemical: Dinyliodonium chloride is used as a reagent for electrolic nylation . It is used as a reactant for copper-catalyzed cross coupling reactions of purinesband arylation of ani is involved in the preparation of acetylenic arylselenide and (arylmethylene)oxindoles. Further, it is employed in the preparation of aryl alkynes through Sonogashira coupling reactions.
