Heterogeneous catalytic asymmetric hydrogenations with modifiers of axial chirality

Studies have been made in heterogeneous hydrogenations on the possible enantioselective effects of precursors of binol-phospates, which proved to be active and effective chiral ligands in homogeneous catalysis. It was to find out, whether a modifier with axial chirality could be used in heterogeneous hydrogenations if it meets certain structural requirements. Our results show that while the conversions reach 100%, the enantiodifferentiation was negligible.
