Metallkomplexe mit Tetrapyrrol‐Liganden. 68. Synthese wasserlöslicher Osmium‐Porphyrin‐Komplexe

Abstract: Die Synthese von Osmiumtetraphenylporphyrinaten mit funktionellen Gruppen in den para‐Stellungen der Phenylreste wird beschrieben. Durch Sulfonierung der entsprechenden para‐unsubstituierten Komplexe erhält man den Carbonylosmium(II)‐Komplex [OsCO(TPPS4)H2O]4− oder den Dioxoosmium(VI)‐Komplex [OsO2(TPPS4)]4− [(TPPS4)6−: Hexa‐Anion des Tetrakis(4‐sulfonatophenyl)porphyrins]. Aus der Dioxoverbindung entsteht durch Reduktion in Gegenwart von 1‐Methylimidazol (1‐Meim) der Osmochrom‐Komplex [Os(TPPS4)(1‐Meim)2]4−, … Show more

“…Water-soluble osmium(II) porphyrinates with sulfonate [1,[12][13][14] or phosphonate groups [15] can undergo reversible redox reactions, and because of this behavior are good cytochrome models. The aim of this work was to prove whether osmium(II) porphyrinates with carboxylate groups show the same redox behavior.…”

“…Osmium porphyrin was synthesised by a combination of the method reported by Che et al [18] and that of Buchler [21]. Osmium was inserted into protoporphyrin IX dimethyl ester from Os 3 (CO) 12 and purified on a silica gel column [18].…”

“…Osmium was inserted into protoporphyrin IX dimethyl ester from Os 3 (CO) 12 and purified on a silica gel column [18]. The carbonyl was removed by oxidation with t BuO 2 H [21]. After basic cleavage of the dimethyl ester the osmium protoporphyrin IX, the complex was inserted into apoHRP under reducing conditions (Fig.…”
