Olefin , bond dissociation energies reactivity

Oxygen atom transfer reactions from metal-oxo species to phosphines (forming phosphine oxides), alkylsulfides (forming sulfoxides), olefins (forming epoxides), and other substrates depend on the relative X=0 bond dissociation energies in the metal-oxo starting material and the oxidized product the reactivity scale based on bond dissociation energies was proposed.62...
