ABSTRACT
This chapter presents an overview of the coordination chemistry of diaryl sulfide ligands with ruthenium. Ruthenium metal complexes involving organic sulfur donor ligands are of considerable interest in coordination chemistry and can serve as potential models to the biological systems. Diarylsulfides are prone to rearrangement and sulfur redistribution in the presence of ruthenium due to lability of S-S bond. Aryl sulfides are fundamental building blocks, which have the capacity to coordinate with metal atoms to form different structural frameworks, exhibiting interesting functional properties, including biological and catalytic activities. There are many reports of ruthenium Schiff base complexes derived from aminothiophenol which gives mononuclear or binuclear complexes. In these complexes, the ruthenium binds via S and N donor atoms of the Schiff base together with other ligands. The ruthenium disulfide complexes possess interesting catalytic and biological properties. Ruthenium disulfide diamine complexes are found to catalyze the oxidation of primary alcohols into corresponding aldehyde and cyclohexene into cyclohexene-oxide, cyclohexenone and cyclohexenol derivatives.
