有机锡化合物的光电子能谱(XPS)和质谱(MS)研究Ⅱ

X RAY PHOTOELECTRON SPECTROSCOPY (XPS) AND MASS SPECTRUM (MS) STUDY OF ORGANIC TIN COMPOUNDS Ⅱ

本文报道了７种新合成的（Ｚ）－１－［２－（三芳基锡）乙烯基］－１－环庚醇有机锡化合物的ＸＰＳ和ＭＳ结果。通过ＸＰＳ讨论了化合物中不同取代基的存在，对锡内层电子的影响及取代基对Ｏｌｓ结合能化学位移的作用。结果表明，卤素在这里起着重要的作用。通过ＭＳ和ＸＰＳ讨论了不同取代基对Ｏ→Ｓｎ键的影响。

Seven new synthetical (Z) 1 [2 (Triarylstannyl) vinyl] 1 cycloheptanols organic tin compounds were studied by X ray photoelectron spectroscopy and mass spectrum method.The influence of different replacement radical in compounds on the d orbit of tin atom was discussed.The coordinate substance had an effect on the chemical displacement of O ls binding energy.The O→Sn bond was affected by the different replacement radical.The results of X ray photoelectron spectroscopy and mass spectrum show that Cl,Br and I had the important action.
