Process for preparing hydrofluoroethers |
| 摘要 |
Process for obtaining hydrofluoroethers of formula (I): <?in-line-formulae description="In-line Formulae" end="lead"?>A-(R<SUB>f</SUB>)<SUB>n0</SUB>-CF(R<SUB>f1</SUB>)-O-R<SUB>h</SUB> (I)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein a mono- or bifunctional carbonyl compound of formula (IV): <?in-line-formulae description="In-line Formulae" end="lead"?>B-R<SUB>f</SUB>-C(O)R<SUB>f1</SUB> (IV)<?in-line-formulae description="In-line Formulae" end="tail"?> is reacted with at least one equivalent of a fluoroformate of formula (III) <?in-line-formulae description="In-line Formulae" end="lead"?>R-OC(O)F (III)<?in-line-formulae description="In-line Formulae" end="tail"?> in the presence of an ion fluoride compound (catalyst) and of a dipolar aprotic organic compound, liquid and inert under the reaction conditions.
