摘要

Using microwave irradiation and protic ionic liquids (pIL) as co-solvent and catalyst for the synthesis of several diphenylmethyl ethers was achieved. The desired ethers were isolated simply by filtration through a silica plug to remove the pIL and proceeded in high yields (60– 98%). These reactions were extremely rapid (10–30min) and occurred under mild conditions (80° C). This protocol was also successfully applied to the synthesis of thioethers.
