Abstract: Fifteen tris(2-dimethyl-2-phenylpropyl)tin carboxylates were synthesized and characterized by IR and 1HNMR. The results showed that these compounds may be four-coordinated and there are a linear relationship between ΔνCO2 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.

Key words: Neophyltin, Carboxylate, Structure characterization, Bioassay, Acaricidal activity
