A new one-pot method for the preparation of alkynylsulfonateesters from terminal alkynes is reported. A metal-assisted, ultrasound-enhanced nucleophilic acetylenic displacement through the alkynyl(phenyl)iodonium salts provides a direct and rapid access to novel alkynylsulfonates in good yields in a simple one-step procedure.
