| Abstract: | 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. |
