In the early 1980s, Shvo and co-workers reported a molecular ruthenium complex that was active in the catalytic dehydrogenation of alcohols and the hydrogenation of carbonyl compounds. Although the reactions themselves were already known, the ligand represented a new paradigm in bond formation/breaking processes that influences homogeneous catalysis to this day.
