Synthesis of “capped porphyrins”

The synthesis of “capped porphyrins” ( 10 ), ( 18 ), and ( 28 ), and their (chloro)iron(III), iron(II), cobalt (II), and zinc(II) complexes is reported. These complexes serve as models for the active site of the oxygen binding haemoproteins. In addition to reversible binding of dioxygen by each of t...

Description
Summary:The synthesis of “capped porphyrins” ( 10 ), ( 18 ), and ( 28 ), and their (chloro)iron(III), iron(II), cobalt (II), and zinc(II) complexes is reported. These complexes serve as models for the active site of the oxygen binding haemoproteins. In addition to reversible binding of dioxygen by each of the iron (II) porphyrin complexes, the 1-methyl-imidazole-(“C 3-capped porphyrin”) iron (II) complex ( 23 ) reacts reversibly with carbon monoxide, in solution at 25°C.
