Access to well-defined Ruthenium(I) and Osmium(I) metalloradicals

Abstract

Figure Presented Radically complex: Well-defined mononuclear RuI and OsI complexes (see scheme) have metalloradical character, as indicated by EPR spectroscopy and DFT calculations. The RuI and OsI metalloradicals exhibit both one-electron and two-electron redox reactivity. The latter process affords unusual imido complexes with substantial radical character on the {ArN} moiety. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
