Method for aminating mononuclear aromatic compounds and polynuclear compounds containing at least one aromatic ring in the presence of a palladium complex catalyst

摘要

The present invention relates to a novel method of amination of mononuclear aromatic compounds and multinuclear compounds containing at least one aromatic ring. The process of the present invention makes it possible to simply separate the aminated mononuclear aromatic compound or the aminated polynuclear compound containing one or more aromatic rings from the reaction mixture and to reuse the catalyst system used. According to the process of the invention, a mononuclear aromatic compound or a multinuclear compound containing at least one aromatic ring is reacted with a primary amine or a secondary amine in the presence of a palladium complex catalyst containing water, a base, and a water soluble organic phosphine ligand. .
