摘　　要：采用Schlenk技术,在干燥纯氩气保护下,用无水三氯化稀土LnCl3与2-苯基茚以1∶2的摩尔比在THF中反应,得到8种新配合物:(2-ph-Ind)2LnCl(A)[Ln=La(1),Pr(2),Nd(3),Sm(4),Gd(5),Dy(6),Yb(7),Y(8)]。再用(A)和LiN(TMS)2在THF中反应,得到两种新的二(2-苯基茚)稀土有机配合物:(2-ph-Ind)2LnN(TMS)2(B)[Ln=Y(1),Sm(2)]。所有配合物都经元素分析、红外和质谱鉴定。配合物(B)在甲基丙烯酸甲酯(MMA)的聚合反应中显示出一定的活性。Reaction of LnCl_3 with two equivalent 2-phenylindeny lithium in THF results in eight new complexes:(2-ph-Ind)_2LnCl (A). Two novel bis(2-ph-Ind)lanthanide complexes:(2-ph-Ind)_2LnN(TMS)_2 (B) were synthesized by reaction of (A) with LiN(TMS)_2 in THF. All complexes were characterized by elemental analysis, IR and mass spectroscopy. Complexes of type (B) showed activity in the polymerization of methyl methacrylate (MMA).
