ABSTRACT:
Disclosed is a process for the preparation of 2,5-dihydrofuran compounds by contacting an olefinically-substituted ethylene carbonate compound with a catalyst comprising an acidic component and a halogen component. The process is especially useful for the preparation of 2,5-dihydrofuran from vinyl ethylene carbonate (4-ethenyl-1,3-dioxolane-2-one) which is readily available from 3,4-epoxy-1-butene.
