Abstract: 5,6-dihydro-2,3-diphenyl-1,4-dioxene and 5,6-dihydro-2,3-dip henyl-1,4- oxathiin were synthesized by the reaction of benzoin with ethylene glycol or 2-m ercaptoethanol under microwave irradiation. The reaction time was shortened abou t 300-fold and the yields was improved when compaved with classical method.A rapid syn thesis and the mechanism of the reaction has been discussed.
