| titleOfInvention | The preparation method of 2- nitro-4-trifluoromethyl Benzonitriles |
| abstract | The present invention relates to technical field of organic synthesis, more particularly to the preparation method of 2 nitro, 4 4-trifluoromethylbenzonitrile, this method is using 3 nitro, 4 chlorobenzotrifluoride and cyanating reagent as raw material, and reaction is to get 2 nitro, 4 4-trifluoromethylbenzonitrile under the action of metal bromide and cuprous cyanide.The cyanating reagent is selected from least one of ferrocyanide salt.This method is using metal bromide cheap and easy to get as activator, using cuprous cyanide as catalyst, can obtain the catalysis yield identical with nickelous bromide, can significantly reduce the production cost of enterprise.Meanwhile the Non-toxic of reaction reagent can be realized with almost non-toxic ferrocyanide salt progress cyanogenation, meet environmentally protective requirement, be conducive to industrialized realization. |
