Abstract

NEW MATERIAL:A racemate(D2) of the title compound of the formula (× is an asymmetric carbon), having the following properties: Melting point 59W60°C. NMR spectrum (90MHz)δHMSCDCl3:1.15, 1.17 (eachs) 6H; 1.46W1.78(m)2H; 2.77W3.28(m)2H; 6.30(s)2H; 6.90W7.47(m)9H.
USE: An insecticide having a high insecticidal activity against sanitary, agricultural and horticultural injurious insects, and a low toxicity to warm-blooded animals. D2, supposedly having a combination of c and d, one of the racemates produced from the four isomers formed by combination of the absolute configuration of asymmetric carbons at the 1-position of the acid morety in the cis-isomer and at the α-position of the alcohol moiety shows a higher insecticidal activity than the other D1, having a combination of a and b.
PROCESS: D1, alone or containing D2 not attained isomerization equilibrium, is reacted with a basic reagent to be equilibrated, and D2 is separated from the equilibrated mixture.
