Method for catalyzing nitro-arene and amine compound to be synthesized into aromatic amine compounds through palladium/imidazolium salt
-
Paragraph 0071-0075, (2019/10/01)
The invention discloses a method for catalyzing nitro-arene and an amine compound to be synthesized into aromatic amine through palladium/imidazolium salt. The method comprises the steps that in an organic solvent, the palladium/imidazolium salt is taken as a catalyst, the nitro-arene and the amine compound are subjected to a coupling reaction under the function of alkali, and then the aromatic amine compounds are obtained through aftertreatment. The method is simple in ligand synthesis, storage is facilitated, the price is low, the use quantity of ligands is low, the yield of the product is high, and the substrates have high applicability and are suitable for preparing diarylamine and N-alkylated arylamine. The method can be used for synthesizing a series of aromatic amine compounds, andthe aromatic amine compounds have high application value in the fields of pesticides, medicines, materials and the like.
