Abstract

We report the synthesis and characterization of a number of primary amide manganese porphyrins from the reactions of the cationic [(por)Mn(THF)₂]ClO₄ (por = tetraphenylporphyrin dianion (TPP), tetra(p-chlorophenyl) porphyrin dianion (T(p-Cl)PP) and [(OEP)Mn]ClO₄ (OEP = octaethylporphyrin dianion) precursors with excess acrylamide or acetamide. Two six-coordinate [(por)Mn(O[dbnd]C(NH₂)CH[dbnd]CH₂)₂]ClO₄ (por = TPP (1) T(p-Cl)PP (2)) complexes and one five-coordinate [(OEP)Mn(O[dbnd]C(NH₂)CH₃)]ClO₄ (4) complex have been structurally characterized by X-ray crystallography. A sole O binding mode of the primary amide ligands in these complexes has been determined. The redox behavior of the [(por)Mn(O[dbnd]C(NH₂)CH[dbnd]CH₂)₂]ClO₄ complexes has been studied by cyclic voltammetry, showing well-defined reversible reduction couples for both complexes.
