Abstract Allyl bromide reacted with a series of phenols in a novel [bmim]PF₆/H₂O bi-phase system to afford the corresponding aryl allyl ether via the Williamson reaction without the presence of phase transfer catalyst at room temperature. The experiment results showed that the reaction performed in mild condition; the product can be isolated conveniently by simple extraction; the ionic liquid can be recovered and reused for the fifth run uitout the reduction of the yield, the system is benign to the environment.
Key words Aryl allyl ether, Williamson reaction, Ionic liquid/water bi-phase system
