Abstract
NEW MATERIAL:α-Ethynyl-4-fluorobenzyl 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate.
USE: Insecticide having higher insecticidal activity than know substituted benzyl ester, and high vapor pressure and volatility. It has high residual activity, and nevertheless no residual property in the environment. It exhibits remarkable effect even to vermins resistant to organophosphate-type or carbamate-type insecticides. Furthermore, it has rapid activity, and low toxicity to man, animal and fish.
PROCESS: The compound of formulaIis prepared, easily, by reacting α-ethynyl-4- fluorobenzyl alcohol or its reactive derivative with 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylic acid or its reactive derivative in an inert solvent in the presence of a tert-amine at room temperature. The insecticide can be prepared at lower cost than existing pyrethroidal insecticide, and can be used safely.
