sym-Diphenylethane was prepared by reductive coupling reaction in water using iron powder as catalyst and Cu₂Cl₂ 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(Cu₂Cl₂)=1.8:1:0.02, at 90℃, 86.7% yield could be achieved.
