(57) [Summary] (Modified) [PROBLEMS] To provide a novel method for producing an aromatic amine in the presence of a paradaphosphacyclobutane catalyst. SOLUTION: The general formula I Ar- [NR 6 R 7] n the preparation of aromatic amines (I), the presence of a paradigm phosphazenium cyclobutane and a base, and the presence of ionic halide or unsaturated In the presence, a haloaromatic compound of the general formula II Ar-Hal (II) is reacted with an amine of the general formula III R 6 R 7 NH (III) in a solvent at a temperature of 20 to 200 ° C. As a specific example, P-chlorotoluene and diethylamine are combined with trans-di μ-acetate bis [2- [Bis (1,1-dimethylethyl) phosphino] -2- Methylpropyl-C, P] dipalladium (II) and KO React in the presence of tBu to produce 4- (N, N-diethylamino) toluene. |
