Abstract: A process for the preparation of aromatic amines by reducing the corresponding nitro compound with phosphorous acid in the presence of a heterogeneous palladium catalyst is characterised in that a phosphorous acid is employed which can be obtained as a by-product in the preparation of organic acid chlorides from organic acids and phosphorus trichloride. The process according to the invention allows aromatic amines to be prepared economically, in high yield, under mild conditions and in a chemoselective fashion. The process is also advantageous from the ecological point of view since it employs a waste material whose incineration or decontamination would involve high energy consumption.
