Mechanistic studies on electron-transfer reactions from zero-valent ruthenium complexes to organic or inorganic acceptors: Isolation, characterization, and reactivity of the products obtained upon oxidation

The deoxygenation of nitroarenes by Ru(1,2-bis(diphenylphosphino)ethane)(CO);The side-bound-nitrosoarene ruthenium complex reacted with carbon monoxide via insertion into the Ru-N bond, producing a known metallacycle, and the Ru-O bond, producing a novel metallacyclic species. On a longer time scale the later complex was converted to the former. The interconversion was inhibited by carbon monoxide. Kinetics of the insertion and isomerization reactions as well as isotopic labeling studies were also investigated.;The structure of Ru (P(cyclohexyl);Chemical oxidation of Ru(1,2-bis(diphenylphosphino)ethane)(CO)...
