摘要
研究了在硫酸催化下,二茂铁与乙酰乙酸乙酯反应一步合成3-二茂铁基-2-丁烯酸乙酯的新方法。3-二茂铁基-2-丁烯酸乙酯经水解得3-二茂铁基-2-丁烯酸,熔点180~181℃。经苯与石油醚溶解,溶剂自然挥发得深红色菱形晶体。晶体属单斜晶系。空间群 P2_(1/c),α=1.1813(4)nm,b=0.8353(5)nm,c=1.2297(4)nm,β=102.31(3)°,Z=4,V=1.1854nm^3。
In this article,a new one-step synthetic me-thod of 3-ferrocenyl-2-ethyl crotonic ester bythe catalysis of sulfuric acid has been studied.The crystal and molecular structures of 3-ferro-cenyl-2-crotonic acid have been determined byX-ray diffraction.The compound crystallizes inthe monoclinic form,space group P2_(1/c),α=1.1813(4)nm,b=0.8353(5)nm,c=1.2297(4)nm,β=102.31(3)°,V=1.1854nm^3,Z=4.
