| titleOfInvention | Preparation method of ionic liquid and synthesizing method of biphenyl compounds by applying palladium carbon catalysis in ionic liquid |
| abstract | The invention provides a preparation method of ionic liquid and synthesizing method of biphenyl compounds by applying palladium carbon catalysis in the ionic liquid, relates to an ionic liquid and a synthesizing method of the biphenyl compounds, and aims to solve the technical problems of complicated synthesis steps, difficult availability and high price of organic ligand required by a conventional biphenyl compound synthesizing method. The ionic liquid is prepared from 4-methylpyridine, 2-chloroethyl methyl ether, methyl cyanide and activated carbon. The preparation method of the biphenyl compounds comprises the following steps: adding aryl halide, arylboronic acid, palladium carbon and potassium carbonate into the aqueous solution of the ionic solution; stirring in magnetic force, adding saturated NaCl solution, and extracting with ethyl acetate; drying and filtering with anhydrous sodium sulfate, and concentrating in vacuum; performing chromatography with a silicagel column; and eluting to obtain the biphenyl compounds. The ionic liquid participates in promoting palladium carbon catalysis to synthesize the biphenyl compounds along with high yield and easy separation; and the catalyst can be recycled, so that cost can be saved, and operation is simple. |
