    • a value is not different very much among these olefins, the present result suggests that the olefin which forms a more stable olefin adduct is more reactive in this epoxidation reaction if other factors are not different very much; in other words, our results indicate that styrene is more reactive than n -hexene in this expoxidation reaction, as shown in Figure 4. This is because the styrene adduct is much more stable than the n -hexene adduct. Certainly, the experimental work reported that the quantum yield of the epoxidation of styrene is moderately larger than that of n -hexene. (16) However, it is also noted that other factors such as π and π* orbital energies, steric effect, and strain energy, etc., would influence the reactivity.
