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

(SNAr) for the synthesis of liquid-phasecombinatoriallibraries was studied. The real and “virtual” combinatoriallibraries of diaryl ethers were synthesized by the reactions of pentafluoropyridine with phenol and its derivatives. Some criteria for the estimation of the quality of the libraries were formulated. A rational methodology for the preparation of representative combinatorial mixtures on the
