摘要: Chiral compounds prepared from proton sponge building block 8-((2R,5R)-2,5-dimethylpyrrolidin-1-yl)naphthalen-1-amine were found to be effective chiral ligands for obtaining complexes of rhodium(I) and palladium(II) by reaction with [RhCl(cod)]2, PdCl2(cod) or Pd(OAc)2. The bearing triethoxysilane groups immobilized on mesoporous MCM-41 in order obtain new heterogeneous catalysts. Both materials are active the hydrogenation alkenes could recycled without loss activity enantioselectivity.
