    • To investigate a possible biradical character of this TS, a CAS-MCSCF/6-31G*//MP2/6-31G* single-point calculation was performed using a (8,8) active space of 8 electrons and 6 π/π* and 2 σ/σ* orbitals more directly involved in the bond making and breaking. The HF electronic configuration was observed to clearly dominate the multideterminant expansion of the CAS-MCSCF wave function in which the corresponding coefficient has a value of 0.91. Therefore, nondynamical electronic correlation is expected to play a minor role in this part of the PES.

    • In general, for the nonsubstituted systems studied in this work, the MP2//HF and MP2 relative energies manifest a good agreement. In addition, the solvation energy calculated on gas-phase optimized structures (not detailed here) compare well with that calculated on structures optimized in solution and reported in Table 3.
