rel-(1R,3R)-3-(2-Chloro-3,3,3-trifluoro-1-propen-1-yl)-2,2-dimethylcyclopropanecarboxylic acid Use and Manufacturing
The preparation method is to put the metered sodium hydroxide solution and solvent into the reaction kettle, start stirring, and put cis-trans-3-(2, 2-dichloro-3, 3, 3-trifluoropropanyl)-2, 2 -Methyl dimethylcyclopropane carboxylate, heated to reflux temperature, until the reaction is complete, about 6h, recover the solvent, after adding hydrochloric acid to adjust the pH value, etc., move it into the separation kettle and pass carbon dioxide, white solid gradually Precipitation from the solution until the precipitation is complete and then filtered to obtain a white powdery solid Z-cis cyfluthrin (also known as kung fu acid).
Z-cis-cyfluthrin is an intermediate for the preparation of lambda-cyhalothrin (cyfluthrin), tefluthrin, bifenthrin and other pyrethroids. It is one of the varieties of chrysanthemum acid which is an important intermediate for the synthesis of pyrethroid insecticides. It can be used to synthesize highly effective pyrethroids.
