Patent

CA 2362695

The invention provides a process for producing a fluorine-containing compound from an inexpensive material. Namely, Compound I such as R A CH2 OH is reacted with Compound II such as XCOR B to form Compound III such as R A CH2OCOR B, followed by fluorination in a liquid phase to form Compound IV such as R AF CF2 OCOR BF, which is converted to Compound V such as R AF COF and/or Compound VI such as R BF COF. R A is an alkyl group or the like, R B is a perhalogenoalkyl group or the like, R AF and R BF are fluorinated R A and R B and X is halogen.

L'invention concerne un procédé de production d'un composé de fluor à partir de matières peu onéreuses. Ce procédé consiste à faire réagir un composé (I), par exemple R<A>CH2OH, avec un composé (II), par exemple, XCOR<B>, afin d'obtenir un composé (III), par exemple, R<A>CH2OCOR<B>, à fluorer ce composé (IV), par exemple, R<AF>CF2OCOR<BF>, et à convertir ce composé (IV) en un composé (V), par exemple, R<AF>COF et/ou en un composé (VI), par exemple, R<BF>COF. R<A> représente alkyle, etc. ; R<B> représente perhalogénoalkyle, etc. ; R<AF> et R<BF> représentent, respectivement, R<A> et R<B> fluorés ; et x représente halogène.
