4-Chlorophenyl cyclopropyl ketone - Reference Information
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Use | 4-chlorophenylcyclopropyl ketone is an intermediate of the insecticide fluorocyclourea. This product is used for the synthesis of new pyrethroid pesticide cyclopropyl-4-chlorophenone oxime-o-(3-phenoxybenzyl) ether with high biological activity. |
| production method | is derived from the reaction of γ-chlorobutyryl chloride with chlorobenzene. The yield was 68.5%. The preparation method is obtained by the reaction of γ-chlorobutyryl chloride with chlorobenzene. Aluminum trichloride and chlorobenzene were added to the reactor, and a mixture of γ-chlorobutyryl chloride and Chlorobenzene was added dropwise with stirring, maintaining the temperature at 25 to 30 °c. After the addition was maintained for 30min, the reaction was poured into water to separate the oil layer, washed with water, dried over anhydrous magnesium sulfate, and the low boiling material was removed to give a brown oil. KOH was dissolved in methanol, and then added to the above distillation residue, stirred, cooled and filtered, the filter cake was washed with methanol, the filtrate was removed under reduced pressure, the residue was diluted with dichloromethane, washed with water, the oil layer was dried over anhydrous magnesium sulfate, the solvent was removed, and the product was distilled under reduced pressure. |
