某些芳酰基二茂铁及其还原产物—相应醇的色谱行为

以正相薄层色谱和反相薄层色谱为向导，研究了卤本甲酰基二茂铁、１－乙醇基－１＇－卤（代苯甲酰基）二茂铁和卤代苯基二茂铁基甲醇的高效液相色谱和反应相高效液相色谱。该三类化合物卤原子在苯环上取代位置相同时，其比移值Ｒｆ和保留时间ｔＲ呈现出如下一致规律：Ｒｆ（Ｆ）＞Ｒｆ（Ｃｌ）＞Ｒｆ（Ｂｒ）＞Ｒｆ（Ｉ），ｔＲ（Ｆ）＜ｔＲ（Ｃｌ）＜ｔＲ（Ｂｒ）＜ｔＲ（Ｉ）。在ＴＬＣ和ＨＰＬＣ中，Ｒｆ和ｔＲ值则随卤原子在苯环

Chromatographic Behaviour of Some Halogeno-Benzoylferrocenes and Their Reduction Products-Corresponding Alcohols Bao Fengrong

he HPLC and RP- HPLC for Halogenobenzoylferrocenes,1-Acetyl-1'-(Halogenobenzoyl )ferrocenes and Halogenophenylferrocenyl Methanol have been studied with thin-layer and re-versed phase thin- layer chromatography as guiding test.The following rules of R_f and t_R values ofthree type compounds have been measured.When the halogen substituted positions on the ben-zene ring are the same,the R_f values decrease and the t_R values increase with the increase of theatomic radius of halogen in RP-TLC and RP-HPLC. When the molecular weight of the compounds are the same ,the R_f and the t_R values changewith the relative halogen substituted positions on the benzene ring in TLC and HPLC,The retar-dation factor and the retention time of halogenobenzoyl-ferrocenes are and .The retardation factor and retention time ofhalogenophenylferrocenyl methanol are and .
