Insertion of Ni(I) into Porphyrins at Room Temperature: Preparation of Ni(II)porphyrins, and Ni(II)chlorins and Observation of Hydroporphyrin Intermediates

Abstract: Reduced Nickel porphyrins play an important role as enzymatic cofactors in the global carbon cycle (cofactor F430), and as powerful catalysts in solar-to-fuel-processes such as the hydrogen evolution reaction, and the reduction of CO and CO. The preparation of Ni(II)porphyrins requires harsh conditions, and characterization of the reduced species is intricate. We present a very mild, convenient, and high yielding method of inserting Ni into electron rich, and electron deficient porphyrins which at the same tim… Show more

“…In contrast to the total synthesis of these macrocycles, an alternative semisynthetic approach to nickel‐containing corrinoid derivatives starting from B 12 is still lacking. New efforts in this pioneering area are of fundamental interest for a better understanding of the similarities and differences in the properties and reactivities of Ni‐ and Co‐containing cofactors . Applications in medicinal chemistry and environmental sensing can also be envisaged …”

“…[2,5,7] Structural evidence for F430 was first obtained by comparing its characteristic absorption with l max % 430 nm to those of synthetic Ni II -containing hydrocorrin and hydrocorphin deriv-atives. [11][12][13][14] Applications in medicinal chemistry and environmental sensing can also be envisaged.

“…[8][9][10] Neue Bemühungen in diesem Pioniergebiet sind von grundlegendem Interesse für ein besseres Verständnis von Gemeinsamkeiten und Unterschieden in den Eigenschaften Ni-und Co-haltiger Kofaktoren. [11][12][13][14] Anwendungen im Gebiet der medizinischen Chemie sowie als Chemosensoren in Te chnik und Umwelt sind ebenfalls voraussehbar. [15][16][17][18] Ziel dieser Untersuchung war es,m odifizierte B 12 -Derivate mit einem zentralen Nickelion und einem Corrinchromophor mit 12 anstelle von 14 p-Elektronen (Abbildung 1, mittig), ähnlich der Kernstruktur von F430 (Abbildung 1, rechts), zu synthetisieren und näher zu untersuchen.…”
