  摘要：

  摘要β-二甲叉基锂盐L2Li [L2 = {（2,6-Me2C6H3）NC（Me）} 2CH]与无水LnCl3（Ln = Yb，Sm，Nd）在THF中的摩尔比为1：1新的β-二酮化镧系元素络合物L2LnCl（THF）（μ-Cl）2Li（THF）2（Ln = Yb（1），Sm（2），Nd（3））。从甲苯中将配合物1-3重结晶，得到中性配合物L2LnCl2（THF）2（Ln = Yb（4），Sm（5），Nd（6））。配合物4和5在热甲苯中重结晶两次，得到双核配合物L2ClLn（μ-Cl）3LnL2（THF）（Ln = Yb（7），Sm（8））。在热甲苯中将配合物2的母液处理3次，得到了新型三核配合物L2SmCl（μ-Cl）3SmL2（μ-Cl）Li（L2H）（THF）（9）。这些络合物中的每一个都被很好地表征，而络合物3、7和9已经通过X射线衍射结构测定来表征。

  salt-free complex LLn(NPh2)2(THF) [Ln = Yb (3), Nd (4)] in good yield as crystalline solids. Both compounds were characterized crystallographically. The coordinated geometry around the central metal can be described as a distorted trigonal bipyramid. Complexes 3 and 4 showed good catalytic activity for the polymerization of acrylonitrile and high activity for the ring-opening polymerization of ε-caprolactone

  Lithiation of the beta-diketimines (2,6-C6H3R2)NH=C(Me)CH=C(Me)N(2,6-C6H3R2) (R = Me (HL1), Et (HL2)) by nBuLi was followed by metathesis reaction with LnCl(3)(THF)(x) and Y(BH4)(3)(THF)(2) to afford the corresponding complexes L(1)LnCl(2)(THF)(2) (Ln = Gd (1), Nd (3), Dy (4), Er (5), Y (6)), (LGdCl2)-Gd-2(THF)2 (2), and (LY)-Y-1(BH4)(2)(THF) (8), respectively. Treatment of neutral HL1 with Y(CH2SiMe3)(3)(THF)(2) generated the bis(alkyl) complex 7, (LY)-Y-1(CH2SiMe3)(2)-(THF). Upon activation with [PhNHMe2][B(C6F5)(4)] and AliBu(3), complex 6 showed the highest cis1,4 selectivity (99.3%, T-p = 0 degrees C) toward the polymerization of isoprene, while complex 7 had a comparatively low cis-1,4 selectivity, and in contrast, complex 8 was completely inert. The influences of the ortho substituents of the N-aryl rings of the ligands, the types of central metals and cocatalysts, and addition sequence of the catalyst components had been thoroughly investigated. By means of X-ray diffraction and H-1 NMR spectroscopy analyses, the intermediates arising from the stoichiometric reactions among the catalyst components and the probable active species were elucidated, which facilitates further investigation of the mechanism for diene polymerization.
