(FR) PREPARATION ET UTILISATION DU PERFLUORO-4,4'-BIS(2,2-DIMETHYLE-1,3-DIOXOLANE)
Abstract: front page image
(EN)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 nuclear magnetic resonance imaging is also disclosed.
(FR)Le nouveau composé perfluoro -4,4'bis(2,2-diméthyle-1,3-dioxolane) est préparé par fluorination de 4,4'-bis[2,2-bis(trifluorométhyle)-1,3-dioxolane à l'aide de radiation UV ou par réaction de 2,2-bis(trifluorométhyle)-4-iodo-4,5,5-trifluorométhyle-1,3-dioxolane avec du zinc dans de l'anhydride acétique et du chlorure de méthylène. L'injection de perfluoro-4,4'bis(2,2-diméthyle-1,3-dioxolane) dans des tissus de mammifères pour en faciliter l'examen par résonance magnétique nucléaire est également décrite.
