摘要： 丁烯醛在π-烯丙基氯化铁三吡啶配合物作用下,会生成自缩合产物,经色谱-质谱、红外光谱、核磁等手段表征,确认产物为6-甲基-1,3环已二烯基甲醛。推测反应机理是丁烯醛与π-烯丙基氯化铁三吡啶配合物进行配位体交换,然后与另一丁烯醛分子加成环化而成。由于配合物中配位体的定位作用,大大提高了反应的选择性而未见其它副反应发生。

关键词: 丁烯醛, 自缩合反应, π-烯丙基氯化铁三吡啶配合物

Abstract: The self-condensation of crotonaldehyde was studied in the presence of tripyridyl π-allyl iron chloride.The product was confirmed as 6-methyl 1,3-cyclohexadiene-1-carboxaldehyde by Gc-MS, IR and 1H NMR.It was suggested that the possible mechanism of the reaction might be the initial ligand exchange of crotonaldehyde with tripyridyl π-allyl iron chloride followed by addition and cyclization with another molecule of crotonaldehyde.The selectivity of reaction was increased greatly by orientation effect of ligand in the complex without side reaction.

Key words: Crotohaldehyde, Self-condensation, Tripyridyl, π-allyl, iron, chloride complex
