of the sodium derivative with YbCl3 yields (C9H7)2Yb·DME (1), an ytterbium(+2) complex with unlinked indenyl ligands. The reaction between (CH2)2(1-Ind′)2Li2 and YbCl3 in diethyl ether with subsequent reduction of the product by sodium metal in THF gives rac-(CH2)2(1-Ind′)2Yb(THF)2, where Ind′=C9H6 (2) and 4,7-(CH3)2C9H4 (3). The structures of the complexes were determined by X-ray structural analysis
通过氢化钠金属化2,2-双(1'-茚)丙烷,然后使钠衍生物与YbCl 3反应,生成(C 9 H 7)2 Yb·DME(1),,(+ 2)络合物与未连接的茚基配体。(CH 2)2(1-Ind')2 Li 2与YbCl 3在乙醚中的反应,然后用THF中的钠金属还原产物,得到rac-(CH 2)2(1-Ind')2 Yb (THF)2,其中Ind'= C 9 H 6(2)和4,7-(CH 3)2 C 9 H 4(3)。通过X射线结构分析确定配合物的结构。
