Robust, efficient, and recyclable catalysts from the impregnation of preformed dendrimers containing palladium nanoparticles on a magnetic support

International audienceThe simple impregnation of γ-Fe2O3(core)/SiO2(shell) magnetic nanoparticles with a dendrimer that contains stabilized Pd nanoparticles is presented as a new method to produce highly efficient heterogeneous catalysts. This technique provides much better stability, recyclability, and activity in C[BOND]C cross-coupling reactions and selective oxidation of benzyl alcohol to benzaldehyde in water than unsupported Pd nanoparticles
