C5H5) (1a) as a condensation product and the amine complex [(η5-C5H4)-NH-(CHO-NO2-2-C4HO)]Fe(η5-C5H5) (1b) as a substitution product in a 1:4 ratio, whereas the reaction between 4-bromo-5-nitrofuraldehyde (5-NO2) and (η5-C5H4NH2)Fe(η5-C5H5) generates only the iminic derivative (2a). The structures of all the complexes were inferred from their FT-IR, 1H NMR, 13C NMR and mass spectra. The molecular structure
5-溴-4- nitrofuraldehyde的反应(4-NO 2)用(η 5 -C 5 H ^ 4 NH 2)的Fe(η 5 -C 5 H ^ 5)产生的席夫碱[(η 5 -C 5 H ^ 4)-N CH-(BR-NO 2 -2-C 4 HO)]的Fe(η 5 -C 5 H ^ 5)(1A),为缩合产物和胺络合物[(η 5 -C 5 H ^ 4) -NH-(CHO-NO 2 -2-C 4 HO)] Fe(η5 -C 5 H ^ 5)(图1b)如在1取代产物:4的比例,而之间的反应4-溴-5- nitrofuraldehyde(5-NO 2)和(η 5 -C 5 H ^ 4 NH 2)的Fe(η 5 -C 5 H ^ 5)仅生成iminic衍生物(2A)。从它们的FT-IR,1 H NMR,13 C NMR和质谱推断所有配合物的结构。二茂铁胺的分子结构(1b)通过X射线晶体学确定显示一个不
