Ruthenium-Catalyzed Reactions for Organic Synthesis

Oxidation of nitric oxide to nitrogen dioxide over Ru catalysts

“…organic synthesis [19], partial oxidation of hydrocarbons [20], Fischer-Tropsch synthesis [21] and ammonia synthesis [22]. Recently, ruthenium catalysts have been applied in the reaction of wet air oxidation of various pollutants [23][24][25] and complete oxidation of volatile organic compounds [26].…”

Highly Selective Hydrogenation of Carbon–Carbon Multiple Bonds Catalyzed by the Cation [(C6Me6)2Ru2(PPh2)H2]+: Molecular Structure of [(C6Me6)2Ru2(PPh2)(CHCHPh)H]+, a Possible Intermediate in the Case of Phenylacetylene Hydrogenation

“…Duckett, Dyson, and co-workers have shown that with parahydrogen, for catalytic hydrogenation reactions with ruthenium clusters, polar solvents favor the catalytic reaction taking place at the intact ruthenium backbone, whereas unpolar solvents favor fragmentation to give mononuclear intermediates. [19] Selective hydrogenation of unsaturated carbonyl compounds: Ruthenium complexes are often used for chemoselective hydrogenation reactions [22] because they are, in general, less active for hydrogenation than rhodium or iridium complexes. As the carbonyl function of ketones is not re- 4 ] under hydrogen pressurization, we investigated the hydrogenation selectivity of this catalyst with organic molecules that contain both C=C and C=O bonds, such as carvone, cis-jasmone, methyljasmonate, or geranylacetone.…”

Synthesis and Catalytic Applications of Ruthenium(0) Nanoparticles in Click Chemistry

“…For example, ruthenium is indispensable as a homogeneous catalyst in a variety of organic reactions. 7 It can easily adopt various formal oxidation states from −II to +VIII in chemical bonds, 8 thus giving rise to many compounds with interesting and often unique properties. There were many reports on supported Ru catalysts.…”
