| 中文摘要 | reactions of neutral amino phosphine compounds hl1-3 with rare earth metal tris(alkyl)s, ln(ch2sime3)(3)(thf)(2), afforded a new family of organolanthanide complexes, the molecular structures of which are strongly dependent on the ligand framework. alkane elimination reactions between 2-(ch3nh)-c6h4p(ph)(2) (hl1) and lu(ch2sime3)(3)(thf)(2) at room temperature for 3 h generated mono(alkyl) complex (l-1)(2)lu(ch2sime3)(thf) (1). similarly, treatment of 2-(c6h5ch2nh)-c6h4p(ph)(2) (hl2) with lu(ch2sime3)(3)(thf)(2) afforded (l-2)(2)lu(ch2sime3)(thf) (2), selectively, which gradually deproportionated to a homoleptic complex (l-2)(3)lu (3) at room temperature within a week. strikingly, under the same condition, 2-(2,6-me2c6h3nh)-c6h4p(ph)(2) (hl3) swiftly reacted with ln(ch2sime3)(3)(thf)(2) at room temperature for 3 h to yield the corresponding lanthanide bis(alkyl) complexes l(3)ln(ch2simc3)(2)(thf)(n) (4a: ln = y, n = 2; 4b: ln = sc, n = 1; 4c: ln = lu, n = 1; 4d: ln = yb, n = 1; 4e: ln = tm, n = 1) in high yields. all complexes have been well defined and the molecular structures of complexes 1, 2, 3 and 4b-e were confirmed by x-ray diffraction analysis. the scandium bis(alkyl) complex activated by alet3 and [ph3c][b(c6f5)(4)], was able to catalyze the polymerization of ethylene to afford linear polyethylene. |
