Elliott, C M

During the eighteen month period covered, to date, by this grant studies have been conducted in the following areas: in an effort to better understand the catalytic oxygenation of C-H, C=C and C-C bonds by certain high valent iron porphyrin-containing enzymes and to try and exploit this chemistry (in the context of a chemically modified electrode), we have concluded an extensive study of the chemistry and properties of a stable Fe/sup III/OH prophyrin. Heteropolynuclear Fe/4Ru porphyrin complexes having unusual electrochemical and spectral properties have been prepared and initially characterized. An electrochemically polymerizable version of one of these complexes forms polymer films capable of catalyzing the electrochemical oxidation of olefins and benzylic methyl groups. Soluble polymers containing a dinuclear molybdenum sulfur complex have been developed and studied. Films cast from solutions of this polymer are insoluble in solvents such as acetonitrile, thus their electrochemical properties can be investigated. These polymers have been shown to catalyze the reduction of azobenzene. Studies have been continued with electronically conducting films made from ester-substituted bipyridine complexes of ruthenium.
