摘要
Twenty-six derivatives of tris[(phenyldimethylsilyl)methyleneltin carboxylates have been pre- pared.All compounds are new and characterized through elemental analysis IR spectra,and ~1H,^(13)C, ^(119)Sn NMR spectral studies.The spectral results showed that all compounds are four coordinated organotin compounds.The Δv(=v(?)-v(?))of them are over 300 cm^(-1).The chemical shifts(δ)of ^(119)Sn of ArCO_2Sn(CH_2SiMe_2Ph)_3 and ArOCH_2CO_2Sn(CH_2SiMe_2Ph)_3 give good straight-line correlation with para-substituent constants.These compounds have good acaricide activity,but their action on the mite are slower than that of Torque.
