Atom-transfer within the coordination sphere of early-late heterobimetallic complexes: rapid deoxygenation of sulfoxides at low temperatures

<p>Extremely rapid oxygen transfer from sulfoxides to a carbonyl ligand to give the corresponding thioether and coordinated CO2 is observed in the reactions of unsupported Zr-Ru heterodimetallic complexes with sulfoxides; this is interpreted to arise from the cooperative reactivity of the two complementary metal complex fragments bound to each other through a highly polar metal-metal bond.</p>
