Abstract: Absolute rate theory within rigid rotor—harmonic oscillator approximation was used for evaluation of the rate constant of the title reaction. In calculations of energy barrier extended basis set (DZ + P) was used with correlation effects included using the fourth-order many-body perturbation theory. Zero point energies and vibration partition functions were computed at the SCF4-31G level. Solvent effect was estimated by means of simple electrostatic continuum model. Reliability of both activation enthalpy at T = 0 К and rate constants is discussed using extrapolation of experimental results for similar reactions.
