    Description / Table of Contents: Synthesis of Iron and Cobalt Complexes of Tetra(2,3-naphtho)-porphine2,3-Naphthalenedicarboxylic anhydride (8) reacts with acetic anhydride to yield 3-oxonaphtho[2,3-c]furan-1(3H)-ylidene acetic acid (9). By treatment with ammonia, 9 is converted into the lactams 10 and 11. Cleavage of H2O and CO2 from 10 gives the benzisoindole derivative 12(Scheme). Tetra(2,3-naphtho)porphinatozinc (2,3-TNPZn) (13) is obtained by reaction of 10, 11, or 12 with zinc acetate; metal-free tetra(2,3-naphtho)porphine (2,3-TNPH2) is formed when 13 is demetalated by trifluoromethanesulfonic acid. 2,3-TNPCo is obtained by reaction of 2,3-TNPH2 with cobalt(II) acetate in pyridine and converted into the pentacoordinated 2,3-TNPCoCN (14) and 2,3-TNPCoCl (15) by treatment with KCN and SOCl2, respectively. Reaction of 1-[2,3-dihydro-1-hydroxy-3-oxo-(1H)-benz[f]isoindole]acetic acid dihydrate (10) with iron(II) acetate yields tetra(2,3-naphtho)porphinatoiron(II) (2,3-TNPFe). Monomeric, bisaxially substituted complexes 2,3-TNPFeL2 with L = py (16), c-HxNC (17), and dib (18) are prepared from 2,3-TNPFe and characterized spectroscopically. The bridged compounds [2,3-TNPFe(L)]n with L = dib and pyz are prepared by reaction of 2,3-TNPFe with L = dib and pyz are prepared by reaction of 2,3-TNPFe with these linear bidentate ligands. As a result of the low oxidation potential of the macrocycle, all of the tetra(2,3-naphtho)porphinato compounds prepared here show comparatively high powder conductivities.
    Notes: 2,3-Naphthalindicarbonsäureanhydrid (8) reagiert mit Essigsäureanhydrid zu 3-Oxonaphtho[2,3-c]furan-1(3H)-ylidenessigsäure (9), die mit Ammoniak in das Lactam 10 bzw. 11 übergeführt wird. Durch Abspaltung von H2O und CO2 aus 10 entsteht das Benzisoindolderivat 12 (Schema). Durch Umsetzung von 10, 11 oder 12 mit Zinkacetat wird Tetra(2,3-naphtho)porphinatozink (2,3-TNPZn) (13) und daraus mit Trifluormethansulfonsäure durch Demetallierung Tetra(2,3-naphto)porphin (2,3-TNPH2) erhalten. Aus 2,3-TNPH2 wird mit Cobalt(II)-acetat in Pyridin Tetra-(2,3-naphtho)porphinatocobalt(II) (2,3-TNPCo) gewonnen, das mit KCN zum pentakoordinierten 2,3-TNPCoCN (14), mit SOCl2 zu 2,3-TNPCoCl (15) reagiert. Tetra(2,3-naphtho)porphinatoeisen(II) (2,3-TNPFe) entsteht bei der Reaktion von 1-[2,3-Dihydro-1-hydroxy-3-oxo-(1H)-benz[f]isoindol]essigsäure-Dihydrat (10) mit Eisen(II)-acetat. Aus 2,3-TNPFe werden die monomeren, bisaxial substituierten Komplexe 2,3-TNPFeL2 mit L= py (16), c-HxNC (17) und dib (18) hergestellt und durch spektroskopische Methoden charakterisiert. Durch Umsetzung von 2,3-TNPFe mit linearen zweizähnigen Liganden werden die überbrückten Verbindungen [2,3-TNPFe(L)]n mit L = dib und pyz gewonnen. Infolge des niedrigen Oxidationspotentials des Makrocyclus zeigen alle hier dargestellten Tetra-(2,3-naphtho)porhinato-Verbindungen vergleichsweise hohe Pulverleitfähigkeiten.
