Abstract

Abstract: ¹H NMR of four new kinds of azole compounds containing sillcon were investigated, they are 1-trimethylisilicoNO_xy-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 δ_H of Me₃SiO; the δ_H of Me₃SiO 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 δ_H of CH and σ_p was obtained for compound Ⅰ.

Key words: ¹H NMR, Azole, Shielding effect, Subustituent effect
