WebA biomimetic non-heme iron ( III )-halide complex, [Fe III (TPA)Cl 2] +, was first synthesized and judiciously employed by Que and co-workers for sp 3 C–H halogenation. 4 The iron ( V )-oxo-halide, [Fe V (TPA) (O) (Cl)] 2+, was proposed as the key intermediate for the halogenation reaction. WebSo heme is the prosthetic group in Hemoglobin, Myoglobin and Cytochrome b, c, and c 1. The Fe – porphyrin prosthetic group is, with the exception of two propionate groups, hydrophobic and planar. Heme become an integral part of the globin proteins during poly peptide synthesis.
