Abstract
A catalyst comprising a chiral transition metal-(1,2-bis(2,5-dialkylphospholano) complex immobilised on a specific zeolitic support useful for the hydrogenation of prochiral substrates.
Claims12
A catalyst comprising a chiral transition metal-(1,2-bis(2,5-dialkylphospholano)benzene) complex immobilised on a zeolitic support having
- a molar ratio SiO2/Me2O3 of between 5 and 50 wherein Me designates an element of valence 3 and
- an external surface area, as developed by pores having a mean diameter higher than 0.8 nm, of at least 90 m2/g.
