Synthesis of diethers derived from dianhydrohexitols by phase transfer catalysis under microwave

A series of new diethers were obtained by alkylation of dianhydrohexitols under microwave (MW) in phase transfer catalysis (PTC) conditions. The products were synthesized in good yields (>90%) within a few minutes. The yields are dramatically improved when compared to conventional heating under the same conditions, in spite of similar profiles of raising in temperature.
