摘　　要：sym Diphenylethane was prepared by reductive coupling reaction in water using iron powder as catalyst and Cu 2Cl 2 as cocatalyst. The product was characterized by infrared analysis, H NMR analysis and melting point measurement. The effects of catalyst molar ratio and reaction temperature were examined. The results showed that on the condition of n (benzyl chloride)∶ n (Fe)∶ n (Cu 2Cl 2)= 1 8∶1∶0 02, at 90 ℃, 86 7% yield could be achieved.sym Diphenylethane was prepared by reductive coupling reaction in water using iron powder as catalyst and Cu 2Cl 2 as cocatalyst.
