摘要: 96 novel sulfur(oxygen) containing 1-aryl O-benzyl oximes were synthesized by the reaction of sulfur(oxygen) containing 1-aryl oximes with the corresponding halides of pyrethriod alcohols in the presence of sodium hydroxide and phase transfer catalyst or with triethylquaternary ammonium salts of halides of pyrethriod alcohol in the presence of sodium hydroxide. The title compounds were identified by MS, (1)H NMR, IR spectra and elemental analyses. Bioassay showed that these compounds showed remarkable insecticidal activities against homopteran and lepidopteran pests. C(74) and C(93) showed a medial effective dose [LC(50)/(mg.L(-1))] of 1.4, 0.63 and 0.31, 1.2 against oriental army worm and leafhopper respectively, the LC(50) values of compounds C(74) and C(93) were better than that of the commercialized insecticide fenvalerate.
