Metallkomplexe mit Tetrapyrrol‐Liganden, III. Darstellung von Metallkomplexen des Octaäthylporphins aus Metall‐acetylacetonaten

Abstract: Die Metall-acetylacetonate M(acac)z (M = Mg, Co, Ni, Cu, Zn), M(acac)3 (M = Al, Sc, V, Cr, Mo, Mn, Fe, Co, In, Ce), MO(acac)2 (M = Ti, V), MoOz(acac)z und M(acac)4 (M = Zr, Th) werden mit Octaathylporphin [ l ; (OAP)Hz] umgesetzt (Tabb. 1 und 2). Abgesehen von Komplexen der Metalle Ce und Th werden die Octathylporphin-Chelate 2-5 (Tab. 3) erhalten. Als gunstigstes Losungsmittel fur die Umsetzungen hat sich Phenol erwiesen : diesem ist Imidazol nur im Falle des Sc(acac)3 wegen der Saurelabilitat der bisher nich… Show more

“…The extent of this doming for the title compound can be seen from the out-of-plane displacement of the 24-atom porphyrin core. The related diacetate derivatives [(OEP)Zr(OAc)2] and [(OEP)Hf(OAc)2] (OEP is 2, 3,7,8,12,13,17,18-octaethylporphyrinato) also exhibit similar geometric features, with eight-coordinate metal centers, bidentate cis-acetate ligands and domed porphyrin cores (Buchler et al, 1971;Hoard, 1975 (Brand & Amold, 1993), [(TPP)ZrC12].thf (Kim, Whang, Kim & Do, 1993) and [(OEP)Zr(CH2SiMe3)2] (Brand & Arnold, 1992), where Tol is toluene and thf is tetrahydrofuran. All of the zirconium and hafnium porphyrins were shown to have cis coordination of ligands, with the metal positioned above the N4 porphyrin plane.…”
