  摘要：

  SmCl3 与 1 当量的 KL（L = [DippNC(Me)CHC(Me)NDipp]; Dipp = 2,6-i-Pr2C6H3）在 THF 中反应，高产率地得到了二聚体钐二氯化物 LSmCl2(THF)Cl2SmL (1)。1 与 NaN(SiMe3)2、KNHAr（Ar = 2,4,6-t-Bu3C6H2）、KBHEt3 和 KCp*（Cp* = C5Me5）反应，生成了各种新化合物：LSmClN(SiMe3)2 (2)，LSm[N(SiMe3)2]2 (3)，LSmNHAr(HBEt3) (4)，LSm(NHAr)2 (5)，和 LSmCp*Cl (6)。1 与一个当量的 NaN(SiMe3)2 反应后再用过量的 AlMe3 处理，得到了独特的双金属钐四聚体 Cl3L2Sm2(AlMe4)2Sm2L2Cl3 (7)。6 与 LiMe 或 LiCH2SiMe3 反应，优良地得到了 LSmCp*Me (8) 和 LSmCp*CH2SiMe3 (9)。用 B(C6F5)3 在甲苯中对 8 进行甲基抽取，生成了阳离子硼酸盐物种 (LSmCp*)[MeB(C6F5)3] (10)。通过 X 射线单晶分析确定了 1–7 和 9 的分子结构。

  Reaction of beta-diketiminate lanthanide dichlorides LLnCl(2)(THF)(2) (L = [(2,6-iPr(2)C(6)H(3))NC(CH3)](2)CH}(-)) with 2 equiv of NaN(SiMe3)(2) in toluene afforded lanthanide amide complexes supported by a dianionic beta-diketiminate ligand L', L'LnN(SiMe3)(2)(THF) (L' = (2,6-iPr(2)C(6)H(3))NC(CH2)CHC(CH3)N(2,6-iPr(2)C(6)H(3))}(2-), Ln = Yb (1), Y (2), Gd (3), Sm (4)), in moderate yields via deprotonation of L. Addition of a small amount of THF led to an increase of the yields of 1-4. Lanthanide metals have a great influence on the deprotonation of L. The same reaction with LNdCl2(THF)(2) did not afford the analogous complex L'NdN(SiMe3)(2)(THF), but the normal diamide complex LNd[N(SiMe3)(2)](2) (5) was isolated instead. The metathesis reaction of the triply bridged dichlorides of Sm, LSmCl(mu-Cl)(3)SmL(THF), with 2 equiv of NaN(SiMe3)(2) yielded the diamide complexes LSm[N(SiMe3)(2)](2) in toluene, while complex 4 was formed instead in a mixture of toluene and THF. In contrast, the same reactions with LYbCl(mu-Cl)(3)YbL(THF) either in toluene or in a mixture of toluene and THF both afforded 1. Treatment of 4 with [HNEt3][BPh4] in THF at room temperature gave the novel cationic Sm beta-diketiminate amide complex [LSmN(SiMe3)(2)(THF)(2)][BPh4] (7) in good yield. Complexes 1-5 and 7 have been confirmed by single-crystal X-ray structural analyses. The mechanism of deprotonation of L was discussed.
