文摘

A new support for Pd(II) was synthesized via the functionalization of Fe₃O₄ nanoparticles with N-(2-aminoethyl)acetamide. PdCl₂ was anchored to the support for obtaining a heterogeneous magnetically recoverable catalyst for Pd(II). High yield and excellent selectivity were obtained for the green epoxidation of styrene derivatives using H₂O₂ as a green oxidant in H₂O as the solvent at 100 °C. Also, the recovered catalyst is applicable for four times without significant decrease in yield.
