摘要 The geometries of the reactants, transition states, intermediates and products for the titled reactions are optimized with CAS(17,13)/cc pVDZ, CAS(9,7)+1+2/cc pVDZ and CAS(9,7)+1+2/cc pVTZ. All stationary points are characterized with vibrational analysis, and the rate constants for the titled reaction are computed with transition state theory. The obtained values are in good agreement with the experimental ones.
