摘　　要：讨论了4种新型含硅唑类化合物的1HNMR谱，它们是1-三甲基硅氧基-1-芳基（叔丁基）－2一唑基乙烷（1：1，2，4-三唑；2：咪唑；3：苯并三唑；4：苯并咪唑）．芳基对Me3SiO的化学位移影响很小，而不同唑基屏蔽作用的差异影响Me3SiO的化学位移，其影响的次序为：此结果得到了分子力学计算的证实．化合物1中1位次甲基质子的化学位移（δH）与芳基对位取代基的取代基常数σp存在良好的线性关系，1H NMR of four new kinds of azole compounds containing sillcon were investigated, they are 1 -trimethylisiliconoxy - 1 - aromatic - 2 - azole - ethane (Ⅰ: 1, 2, 4 - triazole; Ⅱ: imidazole; Ⅲ:benzotrizzole;Ⅳ: benzomidazole). The aromatic (R1) group has no obvious influence on δH of Me3SiO; the δH ofMe3SiO were affected by shielding effect of different azole groups (R), the order is:The result has been proved by Molecular Mechanics Calculation.An good linear relationship between δH of CH and σp was obtained for compound Ⅰ.
