catalyzed aerobic oxidation (cf. 1 → 15). The iron hydride
intermediate IV reacts with an oxidized form of the hybrid catalyst
(IIdox) to regenerate Ia’. The reduced form of hybrid catalyst
(IIdred) reacts with molecular oxygen to give an oxidized hybrid
catalyst (IIdox). For the details of the different intermediates
involved in the reoxidation of IIdred to IIdox, see our previous
report.[13c]
In conclusion, we have developed an iron-catalyzed
biomimetic aerobic oxidation of N-heterocycles under aerobic
conditions using a bifunctional hybrid catalyst (Co(Salophen)-HQ)
as an efficient electron transfer mediator (ETM). A range of N-
heterocycles were oxidized to their corresponding aromatic
heterocycles in good to excellent yields using the iron-catalyzed
aerobic oxidation developed.
