Patent ID: 8399680

Claim:
A process for the preparation of arylamines of formula R 0 —(NH 2 ) n , where R 0 is an aromatic radical and n is between 1 and 3, said process comprising the following steps: a) preparation of a reaction medium comprising: 1) an aromatic compound carrying at least one leaving group, of formula R 0 —Y m , in which R 0 is an aromatic radical and Y is a leaving group, m being between 1 and 3; 2) an aqueous ammonia solution; 3) a catalytic system comprising a complex selected from the group consisting of Cu/β-diketone and Fe/β-diketone; 4) optionally a base; and 5) optionally a solvent; b) heating said reaction medium to a temperature of between 20° C. and 200° C.; c) carrying out the reaction; and d) extracting and isolating the arylamine R 0 —(NH 2 ) n formed, wherein the R 0 radical of the aromatic compound carrying a leaving group is a monocyclic or polycyclic and aromatic or heteroaromatic radical comprising from 2 to 20 atoms.
