Oxygen atom insertion into metal carbon bonds is a key step for metal-mediated hydrocarbon partial oxidation. Few examples have been reported, especially oxy-insertion into non-d0 metal complexes. Cp*Fe[P(OCH2)3CEt]2Ph (Cp* = pentamethylcyclopentadienyl) reacts with Me3NO in THF (THF = tetrahydrofuran) under photolysis or ambient light to ultimately form PhOH. Studies indicate that photolysis assists with dissociation of P(OCH2)3CEt. With other oxidants (e.g., periodate), the C�C coupling product Cp*Ph is observed. The analogous CpFe[P(OCH2)3CEt]2Ph and Cp*Fe[P(OCH2)3CEt]2Me exhibit similar reactivity.
