The steric and electronic influence of various substituents at different positions of the fluorenylidene fragment effects the catalytical properties of the MAO activated bis(fluorenylidene) complexes [C13H8−nRn(CH2)2C13H8−nRn]ZrCl2 (n=0–2; R=H, alkyl, aryl, (CH)4, OCH3). We report the synthesis and characterization of 27 new ansa bis(fluorenylidene) zirconium dichloride complexes and illustrate
各种取代基中的的芴片段的效果的不同位置的空间和电子影响MAO的催化性质活化双(芴基)配合物[C 13 ħ 8- ñ - [R Ñ (CH 2)2 C 13 ħ 8- Ñ ř ñ ]的ZrCl 2(ñ = 0-2; R = H,烷基,芳基,(CH)4 ,OCH 3)。我们报告了27种新ansa的合成和表征双(芴基)二氯化锆配合物,并说明了它们在乙烯的均相催化聚合中的应用。将获得的结果与已知的双(芴基)配合物进行比较。
