采用浓流酸—甲醇为催化剂 ,以甲苯为溶剂进行二茂铁与一些甲基酮的缩合反应 ,经真空升华除去未反应的二茂铁 ,层析分离分别得到了两种 1 -取代苯基 -1 -二茂铁基乙烯 ,以及六种双二茂铁基烷 .通过元素分析、红外光谱、核磁共振氢谱对这些化合物的结构进行了表征
The condensation reaction between ferrocene and some methyl ketones was carried out using concentrated sulfuric acid - methanol as catalyst and toluene as solvent. The unreacted ferrocene was removed by vacuum sublimation. Two kinds of 1 - substituted phenyl -1 - ferrocenyl ethylene, and six bisferrocenyl alkanes.The structures of these compounds were characterized by elemental analysis, IR and 1H NMR spectra
