An Efficient Ligand Exchange Reaction of (E)-[(β-(Trifluoromethanesulfonyloxy)ethenyl](phenyl)iodonium Triflates with Aryl- and Alkynyllithium Reagents Leading to Diaryl- and Alkynyliodonium Triflates

Reaction of (E)-[β-(trifluoromethanesulfonyloxy)-ethenyl](phenyl)iodonium triflates with aryl- and alkynyllithium reagents gave aryl(phenyl)- and alkynyl(phenyl)iodonium triflates in high yields and selectively. These reactions indicate that ligand exchange takes place efficiently at the hypervalent iodine atom and provides another approach to diaryl- and alkynyliodonium salts.
