High-frequency and -field EPR investigation of a manganese(III) N-confused porphyrin complex, [Mn(NCTPP)(py)2].
We report the first high-frequency and -field electron paramagnetic resonance (HFEPR) study of a Mn(III) N-confused porphyrin (NCP) complex (NCP is also known as inverted porphyrin or 2-aza-21-carbaporphyrin). We have found a striking variation in the electronic properties of the S = 2 Mn(III) ion coordinated by NCP compared to other Mn(III) porphyrinoid complexes. Thus, inversion of a single p...
متن کاملDimeric iron n-confused porphyrin complexes.
A dimeric iron N-confused porphyrin, [Fe(NCTPP)]2 was obtained from the anaerobic reaction of Fe(NCTPP)Br with NaSePh while under aerobic conditions a hydroxo bridged iron dimer with Na bridging the outer-N atoms was obtained and oxygenation occurred on the inner core pyrrolic carbon to form a novel ONCTPP porphyrinic ring.
متن کاملNi(III) complex of an N-confused porphyrin inner C-oxide.
A novel, structurally characterized Ni(III) complex of an N-confused porphyrin inner C-oxide has been synthesized from the oxidation of a Ni(II) N-confused porphyrin using OsO4. Crystal data: C53H40N5NiO.CH2Cl2, monoclinic, space group P2/a (No. 13), a=21.229(1) A, b=8.6451(5) A, c=25.762(2) A, beta=93.004(3) degrees, V=4721.6(5) A3, and Z=4.

N-confused porphyrin tautomers: lessons from density functional theory.
Using first-principle calculations, we characterize the properties of N-confused porphyrins (NCP), with a focus on the differences between the 2H and 3H tautomers. We find that NCP-3H is almost as strongly aromatic as porphyrin, and about twice as aromatic, i.e., remarkably more stable, than NCP-2H, due to the less efficient π-conjugation in the latter form. The deprotonation of the NH-group at...
