摘要

The effect of the m and p-Me, Si group upon the ionization constants of anilines, dimethylanilines, phenols and benzoic acids has been studied and the Hammett U-values determined. These data indicate that the m-MerSi group exerts mainly an electron-releasing inductive effect in all these reactions. The latter group, however, is capable of limited conjugation involving an expansion of the silicon valence shell in the reaction of phenols, ...
