|To get some idea of their achievements
we will look an example of the work done by Noyori.
How do chiral hydrogenation catalysts work?
They are transition metal complexes, often of rhodium or ruthenium.
1. The transition metal binds a chiral ligand to give a chiral
2. The catalyst simultaneously binds H2 and the substrate.
3. The hydrogen can be added in two ways to the double bond in
the substrate to give the different enantiomers.
4. The chiral product is released.
