Trifluoromethanesulfonic acidcatalyzedintramolecularhydroarylation of alkynyl selenides and tellurides is developed for the preparation of cycloalkenylselenide and telluride derivatives through a selective 6- and 7-endo mode. The cycloalkenylselenides and tellurides can be easily converted into a wide range of other valuable functionalities, including cyclic olefins, allylic alcohols, enynes,
