the cyclopentadienyl moiety is a saturated one (six, seven, or eight carbon atoms), with YCl3 in THF in 2:1 and 1:1 molar ratios affords complexes of formula [L2YCl]2 and [(LYCl2·THF)2LiCl·2THF], respectively. Here we report the synthesis, spectroscopic characterization, and X-ray crystal structure of [(L′YCl2·THF)2LiCl·2THF] (L′ = 2-phenyl-4,5,6,7,8-hexahydroazulenyl), together with the crystal structure
稠环配体 (L) 的锂盐与环戊二烯基部分稠合的环是饱和环(六个、七个或八个碳原子)与 YCl3 在 THF 中的反应,摩尔比为 2:1 和 1:1比例分别提供式[L2YCl]2 和[(LYCl2·THF)2LiCl·2THF] 的配合物。在这里,我们报告了 [(L'YCl2·THF)2LiCl·2THF] (L' = 2-phenyl-4,5,6,7,8-hexahydroazulenyl) 的合成、光谱表征和 X 射线晶体结构具有六聚体 [L'YCl(OH)}6·2THF] 的晶体结构,在后者复合物的尝试结晶过程中出人意料地分离了它,并且可能是通过该复合物的部分水解形成的。还测试了新配合物对乙烯和 1-己烯聚合反应的活性。(© Wiley-VCH Verlag GmbH & Co.
