摘要： Tsutsui合成了环戊二烯基Sm、Er、Ho烯丙基化合物,但未见报道相应的轻稀土化合物。Mazzei试图合成纯烯丙基稀土化合物,得到的却是LiLn(ally)4型稀土阴离子络合物。黄祖恩等合成了Li2Ln(allyl)4型络合物。

Abstract: A solution of Cp2NdCl-LiCl-THF was prepared successfully and conveniently. The solution can be used to synthesize bis(cyclopentadienyl) organolanthanoid derivatives. Cp2NdC3H5 was prepared from Cp2NdCl-LiCl-THF solution and C3H5Li(1:1)at-78℃.CpNd(C3H5)2·THF and Li [CpNd(C3H5)3]·2Dioxan were prepared from [Li(THF)2]2 (μ-Cl)4CpNd.THF and C3H2Li(1:2 and 1:3 respectively). The new compounds were characterized by elemental analysis, GC, MS and IR. The spectra of all three compounds show a band characteristic of η3-allyl moieties.
