All of the supported Re(V) complexes examined by XPS yielded binding energies showing only a +7 oxidation state, while examination of an unsupported complex clearly showed both Re(V) and Re(VII) as being present. Unlike previous materials, these complexes had never been demonstrated as oxygen atom transfer catalysts. All materials completely reduced perchlorate to chloride in the presence of 2mM excess Cl- while exhibiting pseudo-first order kinetics. Supported catalyst activity increased with the e--donating ability of the para-substituent on the pyridine ligands. Made available in DSpace on 2015-09-25T22:13:58Z (GMT).
