Lanthanide triflates, Ln(OTf) 3, serve as efficient catalysts for the intramolecular hydroalkoxylation (HO)/cyclization of primary/secondary and aliphatic/aromatic hydroxyalkenes in room temperature ionic liquids (RTlLs). Cyclizations are effective in the formation of five-and sixmembered oxygen heterocycles with Markovnikov-type selectivity. Reaction rates exhibit first-order dependence on [Ln 3+] and [substrate].
