β-Methyl and β-ethyl substitution of silanols has been reported to give small acid weakening effects in an earlier experimental study. In this study, ab initio computations have been used to assess β-methyl and β-ethyl substitution effects and have demonstrated that such effects are very small. Such results contrast with the commonly accepted acid strengthening β-alkyl substitution effects first demonstrated in alcohols.
