Abstract A highly efficient ionic liquid catalyst system for selective alkylation of phenol and anisole with alkenes is described. By using Brønsted acidic triflate ionic liquids containing the SO 3 H group attached to the cation, it was possible to recycle the catalyst and reuse it after a simple workup procedure. Moreover, selectivity towards the monoalkylated products was improved to 93% by using a biphasic system.
