| 中文摘要 | 2,6-diisopropyl-n-(2-thienylmethyl) aniline ( h2l) has been prepared, which reacted with equimolar rare earth metal tris( alkyl)s, ln( ch2sime3)(3)( thf)(2), afforded rare earth metal mono( alkyl) complexes, lln(ch2sime3)(thf)(3) ( 1: ln = lu; 2: ln = y). in this process, h2l was deprotonated by one metal alkyl species followed by intramolecular c-h activation of the thiophene ring to generate dianionic species l2- with the release of two tetramethylsilane. the resulting l2- combined with three thf molecules and an alkyl unit coordinates to y3+ and lu3+ ions, respectively, in a rare n,c-bidentate mode, to generate distorted octahedron geometry ligand core. whereas, with treatment of h2l with equimolar sc(ch2sime3)(3)( thf)(2), a heteroleptic complex ( hl)( l) sc( thf) ( 3) was isolated as the main product, where the dianionic l2- species bonds to sc3+ via chelating n, c atoms whilst the monoanionic hl connects to sc3+ in an s,n-bidentate mode. all complexes 1-3 have been characterized by nmr spectroscopy and x-ray diffraction analysis. |
