A simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using DMSO, TBAI in the presence of K2CO3. We extended the utility of Potassium carbonate as an efficient base for the preparation of ethers. A wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl halides in the presence of efficient base Potassium carbonate. Secondary alkyl halides were easily converted to corresponding ethers in relatively good yields . This is a mild, simple and practical procedure for the preparation of ethers in high yields and suitable times under mild condition.
