摘要：
A method for homogenizing heterogeneous catalyst is described. The method is based on growing polyaminoamido (PAMAM) dendrons on silica-coated magnetic nanciparticles. After the dendronizing process, the silica-coated magnetic nanciparticles are more stable and more soluble in organic solvents. The dendronized particles are phosphonated, complexed with [Rh(COD)Cl](2), and applied in catalytic hydroformylation reactions. These new catalysts are proven to be highly selective and reactive.
