Wilkinson catalyst: For example a Rh-catalyst

For example a Rh-catalyst called the Wilkinson catalyst is an effective hydrogenation catalyst for olefins. The mechanism of the hydrogenation involves a combination of oxidative additions, olefin migratory insertions, and reductive eliminations (Fig. 7 3 5 1). Wilkinson's catalyst is the synthetically effective catalysts containing a dihydride intermediate. Learn its definition, mechanism, preparation, properties Selective Hydrogenation By Wilkinson's Catalyst Wilkinson's catalyst can be used to achieve selective hydrogenations Less substituted and sterically less hindered double bonds are selectively hydrogenated. Exocyclicdouble bonds are selectively hydrogenated over endocyclic double bonds. Cis alkenes are reduced rapidly than trans alkenes. Wilkinson's catalyst (chlorido­tris (triphenylphosphine)­rhodium (I)) is a coordination complex of rhodium with the formula [RhCl (PPh 3) 3], where 'Ph' denotes a phenyl group.
