ETHER DERIVATIVE AND SULFIDE DERIVATIVE, PRODUCTION THEREOF AND MITICIDAL AGENT CONTAINING SAME

摘要

NEW MATERIAL:The compound of formula I (R1 is H or CH3; R2 is R1 or Cl; R3 is H or 1-3C alkyl; Y is O or S; X is R1OCH3, methanesulfonyl or halogen). EXAMPLE:4-(2-Fluoroethoxy)-3-bromobenzyl 1-isopropyl-2,2-dimethyl-2-cyanoethyl ether. USE:An agricultural chemical and a miticide. It has excellent miticidal activity and oviposition-suppressing effect, low phytotoxidity to plants and low toxicity to fish, exhibits remarkable effect even against drug-resistant spider mites, is producible at a relatively low cost and is effective in exterminating mites parasitic to various crops by the application to the habitat of the mite. PREPARATION:The compound of formula I can be produced by reacting a compound of formula II (M is H, alkali metal or alkaline earth metal) with a compound of formula III (Z is halogen) in an organic solvent at 20-100 deg.C in the presence of a base as an acid acceptor when M is H.
