金属有机化合物的分析(Ⅴ)——双(烷基环戊二烯基)二卤化钛、锆、铪的纸色谱与核磁共振谱关系的研究

Analysis of Organometallic Compounds (v)——A Study on the Paper Chromatography and Nuclear Magnetic Resonance of Bis(Alkylpentadienyl)Titanium, Zirconium and Hafnium Dihalides

文献报导,仅Subbotina,A.I.等用纸色谱法研究了Cp_(2)TiCl_(2)与CpTiCl_(5)二化合物的分离。我们试图用薄层色谱法分离双(烷基环戊二烯基)二卤化钛、锆、铪化合物,未获成功。改用纸色谱法,取得良好的效果,并对各类化合物所得Rf值与它们的核磁共振谱的δ值之间的变化关系作了研究。

Paper chromatography and nuclear magnetic resonance for bis(alkylpcntadienyl)-titanium, zirconium and hafnium dihalides have been studied.Decane-heptane-acetone (1:5:6) and decane-cyclohexane-acetonc (1:5:6) solvent systems were used for the separation of bis(alkylpentadienyl)titanium, zirconium and hafnium dihalides by paper chromatography.The results have been discussed based on the relation among the obtained R1, δ values and other molecular characteristics.
