Preparation of resin-bound alkynyl iodonium salts and their application in organic synthesis as alkynyl transfer reagents

摘要

We have synthesized polymer-supported alkynylphenyl iodonium salts. They served as effective alkynyl transfer reagents for the preparation of acetylenic sulfones; the by-product, polymer supported (4-iodostyrene), could be reactivated for reuse numerous times.
