Abstract: Sixteen 2, 2, 5-trisubstituted pentane derivatives were synthesized and screened as newpyrethroids: The structures of the compounds were confirmed by 1H NMR, IR.All the compoundsshowed only a moderate insecticidal activity but a well knockdown effect against housefly.The mortality was about 0~12.5% and the knockdown percentage was about 27.5~100% atthe dose of 0.952μg/housefly.

Key words: Trisubstituted pentane, Non-ester pyrethroid, Insecticide, synthesis, biological activity
