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 ^1H NMR, IR, UV-Vis and elemental analysis. Base on the analysis of the reaction intermediates, a possible mechanism of the reaction is proposed.

Key words: PHENYL GROUP, BENZALDEHYDE P, CYCLOPENTENONE P, DRY METHOD, STRUCTURAL ANALYSIS, AROMATIC ALDEHYDE
