A study on the solution and gas-phase chemistry of Mn(III) and Fe(III) tetraarylporphyrin complexes by fast-atom bombardment mass spectrometry. 2: Synthesis and characterization of molecular complexes

AbstractThe chemical behavior of Fe(III) and Mn(III) tetraarylporphorin (TAP) complexes with N-alkylimidazoles and other suitable ligands was studied by direct reaction in the fast-atom bombardment matrix and in the gas phase. The coordination reaction occurs at the metal center and yields molecular adducts of porphyrin/ligand (PL) and PL2 stoichiometry. Coordinative competition between free and covalently linked ligands can be used to probe the conformation of “tailed” Mn(III)-TAP
