铝醚络合物的27Al和1H NMR研究
摘要:
本实验确证了铝醚络合物AlCl_3·Et_2O在醚中~(27)Al的化学位移为100.9ppm, 半峰宽为125Hz, 而不是文献值50ppm, 160Hz~[2,4]。证实了三氯化铝在乙醚中不是以二聚体Al_2Cl_6形式存在, 而是以AlCl_3·Et_2O形式存在。
铝醚络合物在己烷中~(27)Al的化学位移为102.5ppm, 半峰宽251Hz。次甲基氢的~(1)H化学位移为4.20ppm。实验表明铝醚络合物与自由醚间存在快速交换过程。

ALUMINUM-27 AND PROTON NMR SPECTROSCOPY OF THE ALUMINUM ETHER COMPLEX
Abstract:
The chemical shifts and linewidths for aluminum chloride in ethyl ether have been studied by O'Reilly~[1], Haragushi~[2] and Kidd. But-different values have been reported. Up to now the divergence of shifts and linewidths is still present on this question.
In studying the Ziegler-Natta catalyst, the ~(27)Al NMR datum of AlCl_3 Et_2O complex are very important. So we must re-examine them.
It has been verified that the chemical shifts and Iinewidths of the complex in ether are 100.9 ppm and 125Hz respectively, and no...
