Ferrocenyl-substituted 3-cyano-2-methylpyridines were easily prepared by the sonication of α,β-unsaturated carbonyl compounds substituted by ferrocenes in acetonitrile in the presence of potassium t-butoxide.

ferrocenylsubstituted α,β-unsaturatedketones with thiourea in alkaline ethanol leading to the corresponding dihydropyrimidinethiones. Products were isolated as yellow or orange crystals with yields of 65–95%. Structures were proved by high resolution 1H NMR spectra. Ferrocenylsubstituted dihydropyrimidinethiones have been shown to convert quantitatively into the initial α,β-unsaturatedketones under heating
已经研究了二茂铁基取代的α,β-不饱和酮与硫脲在碱性乙醇中的反应,生成相应的二氢嘧啶硫酮。分离出的产物为黄色或橙色晶体,产率为65–95%。通过高分辨率的1 H NMR光谱证明了结构。已显示二茂铁基取代的二氢嘧啶硫酮在存在水的条件下与碱性乙醇一起加热可定量转化为初始的α,β-不饱和酮。
