Cobalt complexes, electron-transfer reactions manganese

A number of other metal complexes can decompose hydrogen peroxide via reactions analogous to Eqs. (45) and/or (46), including those of cerium813 b copper,823 b cobalt,833 b manganese,84 and silver.85 Many of these electron transfer reactions are thought to proceed via inner-sphere complexes of metal-hydrogen peroxides (M—OOH).84 86... [Pg.287]

His research interests include catalysis by cobalt, iron and manganese, complexes (biomimetic dioxygen activation, catalytic oxidation and carbonylation), as well as kinetics and mechanisms of inorganic reactions in solution (fast redox and electron transfer). [Pg.351]

The reaction of cobalt(II) salen complexes with -quinones results in the formation of a [cobalt(III)-(salen)-(t7-SQ)] complex, where ( >-SQ) represents the semiquinone radical ion. (Similar reactions are observed with iron(II) and manganese(II)-salen complexes, the reactions with these metal centers being more extensive than those for cobalt(II)). In the case of 3,5-di-rm-butyl-t>-benzoquinone, however, the cobalt(III) ligand radical complex has been isolated, and from hyperfine coupling constant studies which are assumed as diagnostic of the extent of electron transfer, the complex is described best as a low-spin cobalt(III) system with a coordinated semiquinone. [Pg.59]
