| titleOfInvention | A kind of 2- Trifluoromethyl-1, the preparation method of 4- naphthoquinone derivatives |
| abstract | The present invention relates to a kind of 2- Trifluoromethyl-1s, the preparation method of 4- naphthoquinone derivatives, in organic solvent by the dissolution of copper catalyst, alkali and togni reagent, the compound of benzaldehyde category that aryl acetylenic ketone replaces is added and forms reaction system, reaction system is reacted 10 hours at 60 DEG C, it is post-treated to obtain 2- Trifluoromethyl-1,4- naphthoquinone derivatives.A step of the invention realizes 2- Trifluoromethyl-1, the synthesis of 4- naphthoquinone derivatives, and combined coefficient significantly improves, and reaction condition is mild, and easy to operate, wide application range of substrates, functional group compatibility is good, using cheap cuprous bromide as catalyst, has applications well prospect. |
