二茂铁衍生物的研究工作报道很多,但对它的α,β-不饱和羰基衍生物的研究却很少,主要是由于这类化合物结构特殊,合成步骤多,产率低。我们首次提出了由二茂铁与乙酰丙酮在低温下经浓硫酸催化一步合成4-二茂铁基-3-戊烯-2-酮的新方法。该法反应条件简易,时间短,产率高达72.3％,为进一步研究这类化合物提供了有效途径。同时,我们还研究了该化合物的酰化反应特性:在无水三氯化铝催化下,分别研究了该二茂铁基α,β-不饱和酮衍 There are many reports on the research of ferrocene derivatives. However, few studies have been made on the α, β-unsaturated carbonyl derivatives, mainly because of their special structure, many synthetic steps and low yield. We first proposed a new method for the synthesis of 4-ferrocenyl-3-penten-2-one from ferrocene and acetylacetone by concentrated sulfuric acid at low temperature. The method has the advantages of simple reaction conditions, short time and high yield of 72.3%, which provides an effective way for further study of these compounds. At the same time, we also studied the acylation reaction of the compound: under the catalysis of anhydrous aluminum trichloride, the ferrocenyl α, β-unsaturated ketone derivatives
