A versatile synthetic protocol for benzyl phenyl ether preparation via O‐alkylation of phenolic oxygen with readily available benzylderivatives was demonstrated. The newly designed procedure was carried out using an eco‐friendly medium, room‐temperature ionic liquid (choline hydroxide), under metal‐ and base‐catalyst‐free aerobic conditions. The reaction platform was also successfully applied to phenol
