本文合成了十五个新的[苯基二甲硅基]锡O,O-二芳基二硫代磷酸酯。测定了它们的IR, ^1H, ^1^3C, ^1^1^9Sn NMR及MS, ^1^1^9Sn NMR的化学位移δ和芳环对位取代基的Hammett常数σ之间存在良好的线性关系。

Fifteen new title compounds, e.g., (PhMe2SiCH2)3SnSP(S)(OPh)2, were synthesized and characterized by IR, 1H, 13C, 119Sn NMR, mass spectrometry and elemental anal. These compounds contain a tetracoordinated Sn atom. A good linear relationship was found between the 119Sn chem. shifts and the para-substituted Hammett constant (s).

Key words: INFRARED SPECTROPHOTOMETRY, MOLECULAR STRUCTURE, MASS SPECTROGRAPHY, NMR SPECTROMETRY, STRUCTURAL ANALYSIS, ORGANO SILICON COMPOUNDS, ORGANO TIN COMPOUNDS, PHOSPHORDITHIOATE
