IMPROVED METHOD FOR THE SYNTHESIS OF PERMETHRIN

The present invention describes an improved method for the synthesis of substantially pure Permethrin (1) having purity greater than 99.5% by Gas Chromatography (GC). The invention also relates to a purification process of Permethrin by recrystallization from methanol-water mixture.

Search for Routes of Synthesis of Permethrin and Chloropermethrin Starting from Halogen-containing Alkenoic Acids

Promising procedures were developed for the synthesis of permethrin and I-chloropermethrin starting from acid chloride, nitrile, and esters of 3,3-dimethyl-2,2,4,6,6-pentachloro-5-alkenoic acid and 3,3-dimethyl-2,2,6,6-tetrachloro-5-alken-4-olide, which were prepared by adding derivatives of trichloroacetic acid to 1,1-dichloro-4-methyl-1,3-pentadiene in the presence of catalytic amounts of monovalent copper ions and amine.
