摘　　要：从四苯基环戊二烯酮与乙二醇缩肉桂醛通过干法在２６０￣２７０℃直接加成并脱ＣＯ，接着经氧化、水解制备了２，３，４，５，６－五苯基苯甲醛，对目标产物的结构进行了＾１ＨＮＭＲ，ＩＲ、ＵＶ－Ｖｉｓ和元素分析表征。在对反应中间产物进行分离、鉴定的基础上提出了该反应的可能途径。2,3,4,5,6 - Pentaphenylbenzaldehyde was synthesized via the direct addition of tetraphenylcyclopenta - 2,4 - dien - 1 - one to ethylene glycol acetal of cinnamaldehyde with elimination of CO at 260 - 270℃ , followed by oxidation and hydrolysis. The structure of the target molecule was characterized by H NMR, IR, UV - Vis and elemental analysis. Base on the analysis of the reaction intermediates, a possible mechanism of the reaction is proposed.
