Catalytic mixture based on partially fluorinated titane and zinc halogenides and their application in the preparation of fluorinated organic compounds |
摘要 |
<p>Liquid phase process for the preparation of organic compounds (I) with≥1 fluorine (F) atom comprises (a) addition of hydrogen fluoride (HF) to an unsaturated carbon-carbon (C-C) group or (b) chlorine-fluorine (Cl-F) exchange with HF on completely halogenated C atom(s) in the starting material. Both reactions are catalysed by metal halide, comprising a (partly) fluorinated mixture of titanium (Ti) chloride or bromide in combination with (partly) fluorinated tin tetrachloride (SnCl4) or tetrabromide (SnBr4), in which the Ti:Sn atomic ratio is 9:1 to 1:9. Also claimed is a (partly) fluorinated mixture (II) of Ti tetrachloride (TiCl4) and SnCl4 with a Ti:Sn atomic ratio of 1:9 to 9:1, preferably 1:2 to 2:1, obtained by reacting TiCl4 and SnCl4 with HF, using a molar ratio of HF:(TiCl4 + SnCl4) of≥4:1, especially≥8:1.</p> |
