摘　　要：以反-4-(反-4’-丙基环己基)环己基甲酸为起始原料,经Kochi反应得到纯度99%以上的液晶中间体反-4-(反-4’-丙基环己基)-1-氯环己烷,收率为75%。探讨了反-4-(反-4’-丙基环己基)环己烷及反-4-(反-4’-丙基环己基)环己烯副产物产生的原因,并对Kochi反应的机理进行了推测。More than 99% purity of liquid crystal intermediate of trans4-（ trans-4＇ -propylcyclohexyl） -1- chloride cyclohexane was synthesized via Kochi reaction with trans-4-（trans-4＇-propylcyclohexyl） cyclo- hexylcarboxylic acid as starting material, the total yield was 75 %. The generation cause of the by-products of trans-4- （ trans-4＇ -propylcyclohexyl） cyclohexane and trans4- （ trans-4＇ -propylcyclohexyl ） cyclohexene was investigated, and the mechanism of Kochi reaction was speculated.
