ΔG and ΔH values were obtained by thermoanalysis of analytical frequency calculations at 298 K and 760 Torr. Transition states were assigned by both performing a frequency analysis with animation of the negative eigenvector and an IRC (internal reaction coordinate) calculation from the transition state along the potential energy surface.
