Iron‐Catalyzed CH Hydroxylation and Olefin cis‐Dihydroxylation Using a Single‐Electron Oxidant and Water as the Oxygen‐Atom Source

Bioinspired oxidation: The hydroxylation of alkanes with retention of the configuration and the cis-dihydroxylation of olefins can be accomplished using [FeII(CF3SO3)2(Me,HPyTACN)] (1) as a catalyst, water as an oxygen-atom source, and cerium ammonium nitrate (CAN) as a single-electron oxidant. The oxidation of CH bonds and CC bonds, as well as water oxidation involves a common reaction intermediate formed by the reaction of CAN and [FeIV(O)(OH2)(Me,HPyTACN)]+.
