| titleOfInvention | A kind of preparation method of boscalid amine |
| abstract | The present invention relates to field of compound preparation, particularly a kind of preparation method of new type bactericide boscalid amine.The method is in polar aprotic solvent or high boiling solvent, and under alkali and quaternary ammonium salt exist, the Suzuki of palladium catalyst to chlorophenylboronic acid and adjacent kharophen bromobenzene is obtained by reacting intermediate product 4 '-chloro-2-kharophen biphenyl; Described intermediate product under concentrated hydrochloric acid exists after deprotection with the condensation of 2-chloronicotinoyl chloride, to obtain final product.The present invention uses Pd (OH)n 2 / C is catalyzer, carries out Suzuki linked reaction, and repeatedly recovery is reused, and existing technology of comparing, saves catalyzer cost greatly, facilitates catalyst recovery to utilize, and avoids the adjacent Iodoaniline of use high cost raw material. |
