| description | PURPOSE:To provide a new phosphoric acid ester derivative useful as an insecticidal miticide, having long residual effect of miticidal activity and extremely low toxicity to warm-blooded animal and exhibiting strong activity against insects and mites resistant to organic phosphorus pesticides. CONSTITUTION:The compound of formula I (R to R are lower alkyl; X and X are H or halogen; Y is 0 or S), e.g. 0-ethyl S-n-propyl 0-[4-(alpha- trifluoromethyl-alpha-methoxy) methyl] phenyl phosphoro-thioate. The compound can be produced by reacting a phenol derivative of formula II with a phosphoric acid chloride of formula III in an organic solvent (e.g. benzere) in the presence of an acid acceptor (e.g. pyridine) usually at 0-50 deg.C. The compound of formula II used as a raw material is obtained e.g. by reacting a compound of formula IV with a compound of formula V in the presence of a base such as potassium carbonate. |
