New chiral oxazoline based-rhodium(I) catalysts: Synthesis, characterisation, heterogeneisation and applications

New chiral oxazoline-based rhodium(I) homogeneous and heterogeneous catalysts have been prepared and fully characterised through 1H and 13C 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 CO and CC double bond.
