3-[2-chloro-2-(4-chlorophenyl)ethenyl]-2,2-dimethyl cyclopropane carboxylic acid - Production method
Its preparation method is that p-chlorobenzoyl chloride and methyl benzoate react in the presence of SnCl4 to obtain 3, 3-dimethyl-4-p-chlorobenzoyl methyl butyrolactone, and then interact with halogenating agent PCl5 in methanol to generate 3, 3-dimethyl-4, 6-dichloro-6-p-chlorophenylhexene [5] methyl acid, which is dehydrochlorinated under, that is to obtain 3-[2-chloro-2-(4-chlorophenyl) vinyl]-2, 2-dimethylcyclopropanecarboxylic acid methyl ester, further saponification and acidification to obtain the corresponding cyclopropanecarboxylic acid.
