Abstract

La présente invention a pour objet un procédé de préparation d amino-benzènes substitués. Elle est caractérisé en ce qu'on effectue l'amination directe de benzènes substitués à l'aide de N-chloro-amines, en présence d'un système redox, au sein d'un milieu réactionnel acide. Elle se rapporte à un procédé de préparation d'amino-phényl-urées et d'amino-carbanylates.The present invention relates to a process for the preparation of substituted amino-benzenes. It is characterized in that the direct amination of substituted benzenes is carried out using N-chloro-amines, in the presence of a redox system, in an acidic reaction medium. It relates to a process for preparing amino-phenyl-ureas and amino-carbanylates.
