Abstract: Fourteen tri[(phenyidimethylsilyl)methylene]-(Ⅰ) and tri[(diphenylmethyisilyl) methylene]tin(Ⅱ) unsaturated carboxylates were synthesized by the reaction of corresponding bis(silylmethylene) stannoxanes with unsaturated carboxylic acids.The IR.1H NMR,119Sn NMR and 29Si NMR spectra of these compounds were studied.The data of IRand 119Sn NMRindicate that these compounds are four-coordinated monomeric organotin compounds.The miticide activities of these compounds depended on the substituted silylgroups.Compounds (Ⅰ) have a good acaricidal activity,but which become zero for compounds(Ⅱ).
Key words: Silylmethylenetin, Unsaturated carboxylate, Miticide activity
