The results showed that these compounds may be four coordinated and there are a linear relationship between Δν CO 2 and the Hammett constants ( σ) of the para substituents of the corresponding substituted benzoates. The bioasay tests show that neophyltin derivatives have a good acaricidal activity and may provide an acaricide for the better activity and economy.展开更多
