新型α，β－不饱和羰基桥联双二茂铁衍生物的合成及其成膜性

Syntheses of New Biferrocene Derivatives Containing a α,β-Unsaturated Carbonyl Bridge and Their Langmuir Monolayers

由３－二茂铁基－２－丁烯酸酯经三步反应制得３－二茂铁基－２－丁烯酰氯，并由它与其自身及与单取代二茂铁经酰化反应合成了４种新的α，β－不饱和羧基共轭桥联汉二茂铁衍生物。以１ＨＮＭＲ、ＩＲ光谱及元素分析表征了这些化合物，并研究了它们形成Ｌａｎｇｍｕｉｒ膜的成膜性．结果表明：这４种新的双二茂铁衍生物皆能在空气／水界面上形成Ｌａｎｇｍｕｉｒ膜．

Ferrocenyl-2-crotonyl chloride was prepared by three-step reactions from 3-ferrocenyl-2-crotonic ester.Four new biferrocene derivatives containing α,β-unsaturated carbonyl bridge have been synthesized by the reaction of 3-ferrocenyl-2-crotonyl chloride with itself or carbonyl ferrocene derivatives and characterized by 1H NMR, IR spectra and elemental analysis. These new compounds are able to form Langmuir monolayers on the surface of water. Surface pressure-area(π～A) isotherms of these compounds were obtained.
