Fluorination agent of organic compounds, in particular, of compounds acetylenic, their process of preparation and their use in the reactions of the addition or substitution nucleophilic

摘要

Fluorination agent of organic compounds hydroxyacetals corresponding to the following general formula: & br / (see appended drawing in bopi) & br / in which q denotes: / p & & p & - or (i) a cation of formula: & br / (see appended drawing in bopi) & br / in which r, r, r and r, which are identical or different, represent an alkyl radical having from 1 to 20 carbon atoms, aryl or aralkyl, the number of carbon atoms in r r r, r being at least equal to 13 and then between 15 and 22, - or (ii) a matrix with carrying functional groups of formula: & br / (see appended drawing in bopi) & br / in which r, r and r, which are identical or different, represent inferior an alkyl radical having from 1 to 6 carbon atoms and n is a mean value between 1,5 and 2,5 then between 1,8 and 2,1. / p & & p & use for the fluorination of compounds acetylenic mono- or bi - active by the addition of hf and for the preparation of compounds organofluorinated by substitution of nucleophilic.
