                                    New chiral oxazoline-based rhodium(l) homogeneous and heterogeneous catalysts have been prepared and fully characterised through H-1 and C-13 NMR, CP-MAS NMR and XPS. The method used for anchoring the catalyst onto silica was found particularly suitable, since the organometallic complexes remained unchanged over the procedure. The catalysts exhibited a moderate activity and enantioselectivity in hydrogenation of C=O and C=C double bond. (c) 2005 Elsevier B.V. All rights reserved.
