聚苯醚键联的二氯二茂钛的合成及催化性能的研究

Studies on synthesis and catalytic property of poly(phenyl ethers)-linked titanocene dichloride

以聚苯醚高分子为载体,采用“一锅法”合成了新的聚苯醚键联的二氯二茂钛衍生物。对合成的配合物进行了元素及光谱分析。研究了配合物对烯丙基苯类化合物异构化反应的催化性能,并讨论了不同条件对反应的影响。ESR 谱证实上述含钛高分子配合物所形成的钛氢配合物具有“位置分离效应”,主要处于非聚合的单分子态。

With poly(phenyl ethers)polymers ascarrier,a new poly(phenyl ethers)-linkedtitanocene dichloride complex was synthesizedby“one-pot”method.The product was identi-fied by elemental and spectral analyses.It wasfound that the isomerizations of allyl benzenesare catalyzed by (?)-Cp_2TiCl_2.The effects ofdifferent conditions on the reaction werediscussed.It was proved by ESR spectra that thetitano-hydrogen derivative of polymer-metalliccomplex showed“position separated effect”.Itexists mainly in the single molecule form.
