In this paper, we describe the synthesis of new highly fluorinated diepoxides from diols of general formula HOCH2 (CF2) nCH2OH which are not often used in organic synthesis because of their strong acidity, resulting in poor reactivity towards polyaddition and polycondensation. These highly fluorinated diépoxides are obtained by condensation of these diols with epichlorohydrin, in basic medium and with the phase transfer catalyst, ...
