Application

The Noyori [(diphosphine) RuCl2 (diamine)] catalysts containing the chiral ligand Xylyl-Phanephos display exceptional activity and enantioselectivity in the asymmetric hydrogenation of a wide range of aromatic, heteroaromatic and α,β-unsaturated ketones.

Reactions are performed under mild conditions at room temperature and typically at low H2 pressures of 2-10 bar. High substrate concentrations of up to 40% w/v are tolerated.

Molar substrate/catalyst ratios of up to 100,000/1 are achieved with excellent reactivity and enantioselectivity using commercial grade substrates and solvents.
