Abstract
(The chemical activation of iron, ruthenium, and osmium carbonyl cluster anions has been achieved by investigating their oxidative electrochemistry and then matching the observed electrochemical oxidation potential with chemical reagents, by the use of oxidative addition in the presence of the required ligand; the dianionic clusters [Fe5C(CO)14]2–, [Ru3(CO)11]2–, [Ru5C(CO)14]2–, [Ru6C(CO)16]2–, [Os5(CO)15]2–, [Os7(CO)20]2–, and [Os10C(CO)24]2– have been found to react with multi-electron donor ligands in the presence of a suitable oxidant.
