    • Our distortion energy is defined as the energy difference between a free molecule and the corresponding frozen moiety in the transition state. For 1, this is different from the approach proposed in ref 10c, the reported value (2.4 kcal/mol) is the difference between interaction energy of 1 and that of the frozen 1 moiety in the transition state. The authors used two set of reference monomers to calculate the two interaction energies. In our cases, 10-13 are not pairs (unlike 1, the acidic and basic centers are incorporated in the same molecule), we thus calculated the distortion energies as defined. Our value of 1 (6.2 kcal/mol) can be obtained via the same approach of ref 10c but using the same reference monomers.

    • Using the mPWlPW91 functional in combination with the SDD basis set for Ru and 6-311++G for H, N, C, and P, De Iuliis et al. predicted the activation free energy of model 14 to be 16.6 kcal/mol (see ref 11f); Hedberg et al. reported an activation free energy of 17.8 kcal/mol at. B3LYP+/ LACVP //B3LYP/LACVP level (see ref 20a); Chen et al. predicted the barrier to be 22.0 kcal/mol using B3LYP functional with 6-31+G for H, N, C, P and LANL2DZ for Ru (see ref 20b).
