摘要：

The addition reaction of propionaldehyde to hexafluoro-2-butyne (1) under gamma-ray irradiation gave trans-6,6,6-trifluoro-4-trifluoromethyl-4-hexen-3-one (2) and 4,5-bis(trifluoromethyl)octa-3,6-dione (3). The latter compound was treated with sulfuric acid to give 2,5-diethyl-3,4-bis(trifluoromethyl)furan (4a). Several reactions, such as bromination, dehydrobromination and oxidation, were carried out to prepare derivatives of 4a.
