The invention concerns a method for preparing a polyaromatic compound comprising a chain of two aromatic cycles and bearing at least an amino group on one of the aromatic cycles. The inventive method is characterised in that it consists in reacting an aromatic compound bearing at least an amino group and a leaving group and an arylboronic acid, in an aqueous medium and in the presence of a palladium-based catalyst.

La présente invention a pour objet un procédé de préparation d'un composé polyaromatique comprenant un enchaînement de deux cycles aromatiques et porteur d'au moins un groupe amino sur l'un des cycles aromatiques. Le procédé selon l'invention est caractérisé par le fait qu'il consiste à faire réagir un composé aromatique porteur d'au moins un groupe amino et d'un groupe partant et un acide arylboronique, en milieu aqueux et en présence d'un catalyseur au palladium.
