摘要
2,3-Perfluoro-1,4-dioxanes of the formula I IMAGE (I) wherein X and Y independently from one another mean F or CF3, are manufactured by reacting carbonyl compounds of the formula II IMAGE (II) wherein X has the same meaning as in formula I, Y' has the same meaning as Y in formula I (F, CF3), and additionally can be Cl and Z=Cl, mesylate [=OSO2CH3] or tosylate=[OSO2C4H6-CH3 (p)], with alkali metal fluorides and/or with ammonium fluoride. The reaction products I, among which those wherein at least one of both radicals X and Y is CF3 are novel compounds, are solvents for highly fluorinated compounds and intermediates in various application fields.
