    • note
    • It is interesting that, as shown in Table 7, the CBS-Q and MCCM results are very close to MPW1KH DFT result. The fact that mPW1PW91 apparently underestimates the barrier for reaction R-1 is not entirely surprising. This finding gives us some confidence that mPW1PW91 does not seriously overestimate the barrier heights for reactions R-2, R-3, and R-4.

    • note
    • V/T rate constants are about four times smaller than the mPW1PW91/6-31+G(d,p) ones for 5a → 7a (as a result of a 0.9 kcal/mol higher barrier height) and about five times smaller for 5a → 6a (as a result of a 1.0 kcal/mol higher barrier height).
