Facile nitrite reduction and conversion cycle of {Fe(NO)}(6/7) species: chemistry of iron N-confused porphyrin complexes via protonation/deprotonation.
Facile nitrite reduction was achieved using [Fe(II)(HCTPPH)NO] as the starting compound to react with NaNO(2). Stoichiometric studies allow the isolation of both {Fe(NO)}(6) and {Fe(NO)}(7) nitrosyl complexes and provide insight into the proton and electron transfer processes during the nitrite reduction. Treating [Fe(CTPP)NO] with acid or oxidizing [Fe(HCTPP)NO] with AgClO(4) yields intermediate [Fe(HCTPP)NO](+). The conversion cycles starting from {Fe(NO)}(6) [Fe(CTPP)NO] to {Fe(NO)}(6) [Fe(HCTPP)NO][ClO(4)] then to {Fe(NO)}(7) [Fe(HCTPP)NO] and vice versa were constructed.
