Abstract

The work presented in this thesis investigates the synthesis of low oxidation state coordination complexes of ruthenium incorporating the anionic ligand, [CpCo(P(O)(OMe)_2)_3]-,(L_(OMe)). Several routes to RuL_(OMe)(H_2O)_3^+ are outlined. These routes produced two major products, possibly related by acid-base chemistry.

A new dimeric ruthenium aquo species with the proposed structure [Ru(III)L_(OMe)(H_2O)(µ-OH)_2OTs_2 was isolated. This complex does not provide a straightforward route to the target monomeric oxo compounds, but could conceivably provide a entry into synthesis of ruthenium dimers containing arnines and other ligands.

Finally, a new route to [Ru(IV)(H_20)(µ-O)]_2OTf_2 was discovered which is more convenient and is higher yielding than the previously published procedure.
