Abstract

Procédé de préparation de N-alkyl- ou N-arylsulfonyloxynaphtalimides de formule ci-dessous, dans laquelle R représente un groupe alkyl- ou arylsulfonyle, tandis que R' et R'' représentent chacun indépendamment l'un de l'autre un atome d'hydrogène, un groupe alkyle, un groupe alcoxy, un atome d'halogène, un groupe N,N-dialkylamino ou un groupe nitro, à partir d'anhydrides d'acide naphtalique correspondants, En utilisant l'eau comme milieu réactionnel, on transforme un anhydride d'acide naphtalique en hydroximide d'acide naphtalique au moyen d'hydroxylamine ou d'un sel d'hydroxylammonium et on fait réagir cet hydroximide d'acide naphtalique, sans isolation intermédiaire, avec un sulfochlorure d'alkyle ou d'aryle pour obtenir un N-alkyl- ou N-arylsulfonyloxynaphtalimide.Process for the preparation of N-alkyl- or N-arylsulfonyloxynaphthalimides of the formula below, in which R represents an alkyl- or arylsulfonyl group, while R 'and R' 'each independently represent an atom d hydrogen, an alkyl group, an alkoxy group, a halogen atom, an N, N-dialkylamino group or a nitro group, from corresponding naphthalic acid anhydrides, Using water as the reaction medium, transforms a naphthalic acid anhydride into naphthalic acid hydroximide using hydroxylamine or a hydroxylammonium salt and this naphthalic acid hydroximide is reacted, without intermediate isolation, with an alkyl sulfochloride or aryl to obtain an N-alkyl- or N-arylsulfonyloxynaphthalimide.
