Abstract

NEW MATERIAL:Optically active α-cyano-3-phenoxybenzyl 2-( 3, 4-methylenedioxyphenyl)-isovalerate.
USE: Insecticide or acaricide, which has some twice to four times activity of the racemic isomer.
PREPARATION: For example, a metal salt of S(+)-2-(3,4-methylenedioxy)isovaleric acid is made to react with an α-halogeno-3-phenoxyphenylacetonitrile to form the S(±) isomer in the acid side of a compound of the formula. Then, preferably the product is dissolved in a solvent of a lower alcohol and crystal seeds are inoculated to cause crystallization at -50W20°C. The crystals precipitated are removed to give the acid-side S(+) isomer of the formula rich in the exemplified compound.
