Abstract
NEW MATERIAL:The compound of formulaI[R1 is H or CH3; when R1 is H, then R2 is group of formula II (X is CH3, Cl, Br, or F), and when R1 is CH3, then R2 is CH3].
USE: Insecticide having excellent knockdown effect and insecticidal effect to hygienic vermins.
PROCESS: The compound of formulaIis obtained by reacting the carboxylic acid of formula III or its reactive derivative with 4-hydroxy-(1-methylpropargyl)-2- cyclopenten-1-one (a novel compound) optionally in the presence of a proper reaction assisting agent. The compound of formula IV can be prepared by reacting furfural with the reaction product of a Grignard reagent and 3-halo-1-butyne in the presence of water and a polar solvent, and isomerizing the resultant intermediate of formula V in the presence of a copper base catalyst.
