Abstract

NEW MATERIAL:3-(4-Chlorophenoxy)-4-fluorobenzaldehyde of formulaI.
USE: A starting material of insecticide of formula II, which is low-toxicity to fishes.
PREPARATION: The reaction between an acetal of formula III (R1, R2 are lower alkyl or incorporate to form alkylene) and an alkali metal salt of 4-chlorophenol is conducted in the presence of copper or its compound, preferably in a solvent, at 100W180°C for 5W20 hours. Then, the reaction product is treated with an acid to give the compound of formulaI.
