| titleOfInvention | 2, 6-diaryl pyridine substance and preparation method thereof |
| abstract | The invention discloses a 2, 6-diaryl pyridine substance and a preparation method thereof, which are prepared by taking 5-oxo-5-aryl valeronitrile and aryl boric acid as reactants to react; a palladium catalyst and an acidic promoter are also added; the palladium catalyst is bis (dibenzylidene acetone) palladium or tris (dibenzylidene acetone) dipalladium; the acidic accelerant is trifluoroacetic acid; the reaction temperature is 80-100 ℃, the reaction time is 12-24 hours, the whole reaction is carried out under normal pressure, the reaction condition is mild, easy to achieve and safe. The method can directly synthesize the target product without separating intermediate products, has simple reaction process and high yield up to 96 percent, greatly simplifies process engineering, reduces energy consumption and has the advantage of high yield; a series of 2, 6-diaryl pyridine substances can be prepared, and the method has strong substrate universality, so that better guarantee is provided for developing related pyridine derivatives. |
