... SCHEME 3. The reactions were carried out in the presence of potassium carbonate in acetone as solvent. The coupling of alcohols with aryl halides is a general and useful route for the synthesis of diaryl ethers. In this regard, Li et al. [19] exploited microwave irradiation in the presence of potass ...
