Abstract: A homochiral ferrocenylphosphine ligand (S, pR)-PPFNH(2) has been immobilized to aminopropylated Kieselgel 100 (AMP-K-100) modified with terephthalaldehyde. The heterogeneous catalytic system Rh(I)/imino-phosphine ligand was examined at an enantioselective hydrosilylation of acetophenone and achieved results were compared to its homogeneous analogue.
