摘 要:乙酰基二茂铁与三甲基腈硅烷反应制得α-氰基-α-二茂铁基乙氧三甲硅烷,经四氢铝锂还原后得到2-羟基-2-二茂铁基丙胺(FcA),用该氨基醇分别与氯化镍,氯化铜,氯化锌,氯化镉,氯化汞反应,制备了氨基醇-镍(Ⅱ)、氨基醇-铜(Ⅱ)、氨基醇-锌(Ⅱ)、氨基醇—镉(Ⅱ)、氨基醇-汞(Ⅱ)五种二茂铁基氨基醇-重金属配合物(用通式M-FcA表示)。用Nexus670FTIR红外光谱仪对二茂铁基氨基醇和五种配合物在4000-400cm^-1范围内测定傅里叶变换红外光谱,对各M-FcA的FTIR主要吸收峰做了经验归属,并将各M-FcA的特征吸收峰与FcA的相应吸收峰作对比分析,结果表明:配合物中-OH,-NH2键的吸收峰位置均向低波数方向移动;C-O,C-N键吸收峰位置向高波数方向移动。说明二茂铁基氨基醇中的氨基、羟基与重金属离子之间形成了配位键。α-cyano-α-ferrocenylethoxytrimethylsilame was prepared by the addition of trimethysilyl cyanide to acetylferrocene.2-Hydroxy-2-ferrocenylpropylamine(FcA) was synthesized by the reduction of α-cyano-α-ferrocenylethoxytrimethylsilame with lithium aluminum hydride. A series of coordinate complexes-FcA-Ni( Ⅱ ), FcA-Cu( Ⅱ ), FcA-Zn( Ⅱ ), FcA-Cd( Ⅱ ) and FcA- Hg( Ⅱ ) were obtained through coordination of this ligand with MCl2 (M=Ni, Cu, Zn, CA and Hg). The FTIR spectra of the complexes and ligand were obtained in the range of 4 000-400 cm^-1. Their major bands were assigned and compared. The results showed that in all complexes some bands(υO-H, υN-H, δO-H, δN-N) were shifted to lower wave number, and some(υC-N, υO-N) were shifted to higher wave number. The aminoalcohol groups and metal ions were bound with coordinated bond.
