| 摘 要： | Two ytterbium complexes stabilized by phenoxy(quinolinyl)amide ligand 3,5-Bu t 2 -2-OC 6 H 2 CH 2 N-8-C 9 H 6 N (L) were synthesized and characterized. Reaction of anhydrous YbCl 3 with 1 equiv. of LLi 2 in THF gave the ytterbium chloride LYbCl(THF)] 2 (1) in 73% yield. A further reaction of complex 1 with equimolar of NaN(SiMe 3 ) 2 in THF afforded the unexpected heterobimetallic "ate"-complex L 2 YbNa(THF) 2 (2) via a ligand redistribution reaction. Complex 2 could also be prepared in high isolated yield by the reaction of anhydrous YbCl 3 with 2 equiv. of LNa 2 generated in situ. Both complexes 1 and 2 were characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction analysis. It was found that complex 2 was an effective catalyst for the addition reaction of aromatic amines to carbodiimides.
