Abstract
Oxy-functionalization of metal–alkyl and −aryl bonds is a key step in potential hydrocarbon oxidation catalysis. However, well-defined examples of M–R to ROH conversion are rare, especially for first-row transition metals. Cp*Fe(CO)(NCMe)Ph reacts with oxygen or hydrogen peroxide to produce benzoic acid. Removing CO from the Cp*Fe(L)(L′)Ph framework allows simple oxygen atom insertion into the Fe–Ph bond. Cp*Fe(P(OCH2)3CEt)2Ph reacts with Me3NO in THF to produce PhOH in high yield when Brønsted acids are added. Studies show that light promotes P(OCH2)3CEt dissociation from Cp*Fe(P(OCH2)3CEt)2Ph, which facilitates the conversion to PhOH. The methyl analogue Cp*Fe[P(OCH2)3CEt]2Me reacts with oxidants to produce MeOH.
