【摘要】 <正> 最近,我们报道了含直链共轭双烯配体和支链共轭双烯配体的金属羰基化合物,丁二烯三羰基铁和异戊二烯三羰基铁与亲核试剂芳基锂在低温下反应,继后用Et₃OBF₄烷基化,分别生成一族新奇的异构化的丁二烯和异戊二烯烷氧基卡宾铁配合物。这些配合物的结构显示的中心金属和烯烃配体的键合方式是非常有趣的。本文选择含环状共轭双烯配体的1,3-环己二烯三羰基铁（1）与芳基锂在低温下进行类似的反应,以观察环烯烃配体的反应活性及其更多还原

【Abstract】 1, 3-Cyclohexadione（tricarbonyl） iron reacted with nucleophiles aryllithium, ArLi（Ar=C₆H₅, m-, p-CH₃C₆H₄, p-CH₃OC₆H₄, p-CF₃C₆H₄）, in ether at low temperature to yield acylcarbonyl lithium salts which on subsequent alkylation with Et₃OBF₄ in aqueous solution at 0℃ or in CH₂Cl₂ at-60℃ gave the corresponding orange-red crystalline products with the composition C₆H₈ （CO）₂FeC（OC₂H₅） Ar. On the basis of elemental analyses, IK, 1H NMR and mass spectral characterization, as well as an X-ray single crystal diffraction study, these new compounds were shown to be isomerized products of cyclohexadiene （dicarbonyl） [ethoxy （aryl） carbene] iron complexes with unusual structure as indicated in the Chinese Text.更多还原
