Abstract

L'invention porte sur un procédé de fabrication du 2-bromo-2,2- difluoroéthanol, qui comprend la réduction d'un dérivé d'acide bromodifluoroacétique, représenté par la formule [1], à l'aide d'un complexe ate-hydrure utilisé en tant qu'agent réducteur. Le 2-bromo-2,2-difluoroéthanol ainsi produit peut être utilisé en tant que matière première pour réaliser l'étape d'estérification, l'étape de sulfination et l'étape d'oxydation, dans cet ordre, permettant ainsi d'obtenir un sel d'acide 2-alkylcarbonyloxy-1,1-difluoroéthanesulfonique, où A représente un groupe alcoxy linéaire ramifié ou cyclique, substitué ou non substitué, possédant de 1 à 20 atomes de carbone, un groupe aryloxy substitué ou non substitué possédant de 6 à 15 atomes de carbone, un groupe hétéroaryloxy possédant de 4 à 15 atomes de carbone ou un atome d'halogène.
