摘　　要：本文研究了羟基肉桂酸类化合物-咖啡酸(CA)在不同条件下采用各种无机单电子氧化剂(Ag_2O、Ag OAc、Cu SO_4、Fe Cl_3和K_3[Fe(CN)_6])的仿生氧化偶联产物。结果表明:无机单电子氧化剂的种类和溶剂对氧化反应有着显著的影响。在Cu SO_4的CH_3CN-H_2O(v∶v=1∶2)溶液中,CA的二聚物(8-8,-Di CA)产率显著提高达75%。In this thesis,we have synthesized their oxidative products by inorganic one-electron oxidants（Ag_2O,Ag OAc,Cu SO_4,Fe Cl_3and K_3[Fe（CN）_6]）in different microenvirmonent.The results reveal that inorganic one-electron oxidants and solvent are very improtant to the oxidative coupling reaction.It was found that the CA in Cu SO_4/mixed solvent（water/acetonitrile,v∶v=2∶1）system could lead to the corresponding dehydrodimers（8-8＇-Di CA）with a high yield（75%）.
