Part I. Cytochrome c oxidase active-site modeling: Synthesis and characterization of new unsymmetrical tris(imidazole- and pyridine-appended) picket-fence porphyrins and their metal complexes. Part II. Toward fullerene-based radiopharmaceuticals: High-yield neutron activation of endohedral holmium-165 metallofullerenes
Part I . Two new unsymmetrical picket-fence porphyrin ligands 1 and 2 and their metal complexes have been prepared as potentially improved structural models for the binuclear (Fe/Cu) Cytochrome c Oxidase (C c O) active site. 1 and 2 have a naphthyl porphyrin superstructure which has been …

Part I. Spin-state isomerism in crystalline (trifluoromethanesulfonato)(meso-tetraphenylporphinato)iron(III). Part II. Toward refined model compounds for the cytochrome c oxidase active site: A new picket-fence porphyrin with short imidazole pickets
Part I. The unsolvated porphyrin compound (Fe$\sp{\rm III}$(TPP)(OSO$\sb2$CF$\sb3$)) has been structurally characterized by single-crystal X-ray diffraction in a monoclinic phase at 293 K and in a triclinic phase at 293, 188 and 103 K. While only one type of molecular site is found in the …

The Design and Application of Ion-paired Ligands to Address Selectivity Challenges in Transition Metal Catalysed Oxygen and Nitrogen Transfer Reactions
… in this field involve the use of chiral ligands on the metal to induce asymmetry and whilst a well-proven approach to enantiocontrol, it is not universally applicable. Our group has developed an alternative approach in which achiral anionic ligands are ion-paired to chiral cations based …

Mechanistic Investigations of Hydrogen and Oxygen Atom Transfer Reactions by Manganese-Oxygen Species
… of synthetic iron(IV)-oxo intermediates bearing porphyrin and non-porphyrin ligands have been successfully investigated as the models of iron enzymes. However, synthetic manganese(IV)-oxo species are also proposed to be the reactive species catalyzing the oxidation reactions of C‒H bonds but the …
