1970年Coutts成功地合成了第一个π-烯丙基稀土配合物(C_5H_5)_2ScC_3H_5。但由于其稳定性差仅有几篇报道。1987年黄祖恩等报道了Li_2Ce(C_3H_5)_5·3D(D为二氧六环)的晶体结构。1991年吴文玲等报道了第二个π-烯丙基稀土配合物(C_3H_5)_2CeCl_5Mg~2(tmed)_2的晶体结构。
In 1970 Coutts succeeded in synthesizing the first π-allyl rare earth complex (C_5H_5) _2ScC_3H_5. However, there are only a few reports due to its poor stability. In 1987, Huang Zuen et al. Reported the crystal structure of Li_2Ce (C_3H_5) _5 · 3D (D is dioxane). In 1991, Wu et al. Reported the crystal structure of the second π-allyl rare earth complex (C_3H_5) _2CeCl_5Mg ~ 2 (tmed) _2.
