    摘要: The novel compound perfluoro-4,4'-bis(2,2-dimethyl-1,3-dioxolane) is disclosed. Its preparation by fluorination of 4,4'-bis[2,2-bis(trifluoromethyl)-1,3-dioxolane using UV radiation or by reaction of 2,2-bis(trifluoromethyl)-4-iodo-4,5,5-trifluoromethyl-1,3-dioxolane with zinc in acetic anhydride and methylene chloride is also disclosed. The infusion of perfluoro-4,4'-bis(2,2-dimethyl-1,3-dioxolane) into mammalian tissue to facilitate inspection thereof by muclear magnetic resonance imaging is also disclosed.
