Ruthenium catalyst is highly active in hydrogenation of aliphatic carbonyl compound and aromatic ring. Hydrogenation is possible without side reaction in mild conditions. When mixing water with reacting system, water becomes a co-catalyst and can show high activity. In addition, sulfur compound has strength against toxins which is exceptional nature as precious metal catalyst. It is quite stable against base or acid, and can be used for reaction in strong acid.
