7-{(N-2，6-R)亚氨甲基)}吲哚(HL1，R=二甲基苯基；HL2，R=二异丙基苯基)与稀土金属三(烷基)S，Ln(CH2SiMe3)(3)(THF)(2)反应，生成了新的稀土金属双(烷基)配合物LLn(CH2SiMe3)(2)(THf)[L=L-1：Ln=Lu。(1a)，Sc(1b)；L=L-2：Ln=Lu(3a)，Se(3b)]和单(烷基)配合物L-2Lu-2(CH2SiMe3)(4a)。烷基化合物1a和4a分别与N，N‘-二异丙基碳二亚胺反应得到相应的酰胺类化合物(LLU)-Lu-1{IPR(2)NC(CH2SiMe3)NiPr2}(2)(2a)和L-2Lu-2{IPR(2)NC(CH2SiMe3)NiPr2}(5a)。
Reaction of 7-{(N-2,6-R)iminomethyl)}lindole (HL1, R = dimethylphenyl; HL2, R = diisopropylphenyl) and rare-earth metal tris(alkyl)s, Ln(CH2SiMe3)(3)(THF)(2), generated new rare-earth metal bis(alkyl) complexes LLn(CH2SiMe3)(2)(THF) [L = L-1: Ln = Lu. (1a), Sc (1b); L = L-2 : Ln = Lu (3a), Se (3b)] and mono(alkyl) complexes L-2 Lu-2(CH2SiMe3) (4a). Treatment of alkyl complexes 1a and 4a with N,N'-diisopropylcarbodiimide afforded the corresponding amidinates (LLu)-Lu-1{iPr(2)NC(CH2SiMe3) NiPr2}(2) (2a) and L-2 Lu-2{iPr(2)NC(CH2SiMe3)NiPr2} (5a), respectively.
