Hydrogenation of Alkenes with Metal Catalysts

Hydrogenation of Alkenes with Metal Catalysts: Stereochemistry

Heterogeneous catalytic hydrogenation of alkenes is syn-stereospecific, i.e. both hydrogen atoms are tranferred to the same side of the π plane. Addition occurs from the less hindered side.


No differentiation is observed if both sides are equal (the π plane is a mirror plane). Enantiope olefins yield the racemate.


Enantioselective catalytic hydrogenation is accomplished with chiral homogeneous catalysts.
