Title
(EN) METHOD FOR PREPARING META-SUBSTITUTED AROMATIC NITROGEN DERIVATIVES
(FR) PROCEDE POUR L'OBTENTION DE DERIVES AROMATIQUES AZOTES SUBSTITUES EN POSITION META
Abstract
(EN)
A method useful for the synthesis of a meta-substituted nitrogen derivative, comprising the step of deaminating an ortho- and/or para-substituted nitroaniline of the aniline function. The method is useful for organic synthesis.
(FR)
