摘要
以SnCl4和2,4,6-(CF3)3C6H2Li、2,6-(CF3)2C6H3Li为原料合成了两种含大吸电子取代基的化合物Sn[2,4,6-(CF3)3C6H2]2Cl2(缩写为SnAr2Cl2)和Sn[2,6-(CF3)2C6H3]2Cl2(缩写为Sn Ar′2Cl2),利用X射线衍射仪和核磁共振谱仪(19F NMR)表征了产物SnAr2Cl2和SnAr′2Cl2的晶体结构.
Two compounds containing large electron-withdrawing substituents, Sn [-2,4, 6- (CF3)3 C6 H2 ]2 C12 (coded as SnAr2 C12 ) and Sn[-2,6-(CF3 )2 C6 H3 ]2 C12 (coded as SnAr'2 C12 ) were synthesized with SnC14, 2,4,6-(CF3)3C6H2Li and 2,6-(CF3)2C6H3Li as the starting ma- terials. The crystal structure of as-synthesized SnAr2 C12 and SnAr^2 C12 was characterized by X ray diffraction and nuclear magnetic resonance spectroscopy (19F NMR).
