Fe-Catalyzed Hydroalkylation of Olefins with para-Quinone Methides

A novel Fe-catalyzed hydroalkylation of olefins with para-quinone methides (p-QMs) for accessing phenols has been developed. In this protocol, various olefins could convert to alkyl radicals and undergo addition to para-quinone methides toward C–C bond formation and aromatization. The reaction conditions are mild and the substrate scopes are broad.
