Technical Notes:
1. The Noyori [(diphosphine) RuClz (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 a,ß-unsaturatedketones.
2.Reactions are performed under mild conditions at room temperature and typically at low Hz pressures of 2-10 bar. substrate concentrations of up to 40% w/v are tolerated
3.Molar substrate/catalyst ratios of up to 1 00,000/1 are achieved with excellent reactivity and enantioselectivity using commercial grade substrates and solvents.
