摘要：

A microwave-assisted three-component reaction was established for the synthesis of aryl alkyl ethers. The reaction was performed under solvent-free conditions in the presence of N-methylimidazole and dialkyl acetylenedicarboxylate to furnish a novel approach to O-alkylation of phenol derivatives in high yield.
