    • The result of the case with the CPCM continuum solvation model to estimate the effect of higher solvation shells is the following: in the reduction of 4-methylcyclohexanone the axial attack is predominant by 0.88 kcal mol-1, and in the reduction of 2-tert-butylcyclohexanone the equatorial attack is predominant by 0.12 kcal mol-1. These results are almost the same as the result of the case in which the effect of higher solvation shells is not considered, showing it should not affect our result significantly
