Oxidatively induced radical chemistry of dicarbonyl η5-cyclopentadienyl iron derivatives of carboxylic acids (Fp–acyl complexes)

Abstract

The 17-electron cationic [Fp–acyl] intermediates generated by cerium ammonium nitrate (CAN) oxidation of Fp–acyl complexes in dry acetonitrile undergo a fast homolytic dissociation leading to alkyl radical species whose subsequent fate is dependent on the structural features and reaction conditions.
