A simple and efficient method has been developed for the synthesis of phenolic ethers using room-temperature ionic liquid, not only as solvent but also as promoter. Ionic liquid was recycled and subsequently reused without any loss of the product. Copyright Taylor & Francis, Inc.

Diaryloxymethanes were prepared by treating phenols with sodium hydride and dichloromethane in N-methyl-pyrrolidinone (NMP) at 40°C.

The formation of ethers was catalyzed by 5,11,17,23,29,35-hexa-p-t-butyl-37,38,39,40,41,42-hexakis(3,6,9-trioxadecyloxy)calixarene (1).It was found that the calixarene-catalyzed reaction of phenol with benzyl bromide in the presence of KOH in CH2Cl2 yields only the O-alkylated product and this reaction proceeds according to Michaelis-Menten type kinetics.The calixarene 1 also catalyzed the reactions of phenols with dichloromethane and 1-chloro-4-nitrobenzene.
