Title (EN) IMPROVEMENT TO THE EXCHANGE AND RELEASE OF AN AMINE FROM ITS CARBAMOYL FLUORIDE
(FR) PERFECTIONNEMENT A L'ECHANGE ET A LA LIBERATION D'UNE AMINE, DE SON FLUORURE DE CARBAMOYLE
Abstract: front page image
(EN)The invention concerns a method for treating an aryl carbamoyl fluoride, comprising in its molecule at least a perhalogenated aliphatic carbon, which bears at least a halogen atom to be exchanged with the fluorine. The method comprises a step which consists in contacting said carbamoyl fluoride with hydrofluoric acid, the hydrofluoric acid/carbamoyl fluoride ratio being maintained during the reaction at a value less than 4, preferably 5. The invention is characterised in that said ratio is not more than 11. The invention is applicable to organic synthesis.
(FR)La présente invention concerne un procédé de traitement d'un fluorure de carbamoyle arylique, comportant dans sa molécule au moins un carbone aliphatique perhalogéné, lequel porte au moins un atome d'halogène à échanger avec le fluor. Ce procédé comporte l'étape de mise en contact dudit fluorure de carbamoyle avec de l'acide fluorhydrique, le rapport fluorhydrique sur fluorure de carbamoyle étant maintenu pendant la réaction à une valeur au moins égale à 4, de préférence à 5, et caractérisé par le fait que ledit rapport est au plus égal à 11. Application à la synthèse organique.
