Title (EN) METHOD FOR NUCLEOPHILIC SUBSTITUTION
(FR) PROCEDE DE SUBSTITUTION NUCLEOPHILE
Abstract:
(EN) The invention concerns a method for the nucleophilic substitution of a hydroxyl function of an alcohol by a nucleophilic group (Nu) other than a fluorine atom, comprising steps which consist in: a) bringing together the alcohol with the nucleophile, then adding SF4 or an aminosulphur trifluoride, thereby causing the desired nucleophilic substitution reaction; b) hydrolysis of the reaction mixture; and c) separating the final product obtained.
(FR) Cette invention concerne un procédé de substitution nucléophile d'une fonction hydroxyle d'un alcool par un groupe nucléophile (Nu) autre qu'un atome de fluor, comprenant les étapes de: a) mise en présence de l'alcool avec le nucléophile, puis addition de SF4 ou d'un trifluorure d'aminosoufre, ce qui conduit à la réaction de substitution nucléophile attendue; b) hydrolyse du mélange réactionnnel; et c) séparation du produit final obtenu.
