| 中文摘要 | treatment of indenyl-modified imidazolium bromide [c9h7ch2ch2(nchchn(c6h2me3-2,4,6)ch)br] ((indh-nhc-h)br) with rare earth metal tetra(alkyl) lithium (ln(ch2sime3)(4)li(thf)(4)) or with (trimethylsilylmethyl)lithium (lich2sime3) and rare earth metal tris(alkyl)s (ln(ch2sime3)(3)(thf)(2)) sequentially afforded the first nhc-stabilized monomeric rare earth metal bis(alkyl) complexes (ind-nhc)ln(ch2sime3)(2) (1, ln = y; 2, ln = lu; 3, ln = sc) via double-deprotonation reactions. complexes 1-3 are thf-free isostructural monomers. the monoanionic ind-nhc species bond to the central metal ion in a eta(5):kappa(1) constrained geometry configuration (cgc) mode, which combine with the two cis-located alkyl moieties to form a tetrahedron ligand core, leading to the chirality of the complexes. under the presence of activators alet3 and [ph3c][b(c6f5)(4)], complex 2 showed catalytic activity toward the polymerization of isoprene to afford 3,4-regulated polyisoprene (91%). |
