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