某些二茂铁丙烯酰胺的结构与红外光谱特征

The Structures and Characteristic Infrared Spectra of N-Alkyl-Ferroceny-lacryloyl Amides and N-Aryl-Ferrocenylacryloyl Amides

总结归属了6种N-烷基二茂铁丙烯酰胺及13种N-芳基二茂铁丙烯酰胺的主要红外吸收谱带和特征,讨论了其红外吸收频率随化合物结构变化的规律。结果表明,氮上取代基从空间效应及电子效应两方面影响化合物红外吸收,主要是对v c-c,v c-o及酰胺Ⅱ带有较大影响。

The characteristic infrared bands of six N-alkyl-ferrocenylacryloyl amides and thirteen N-aryl-ferrocenylacryloyl amides were assigned. The electronic effect and spatial effect of substituents of these compounde on their IR data were discussed. The result's show that the N subsituents have main influence on the v(O-C) , v(O-O) and delta(CNH).
