1990年,Schumann,H.等报道了用双(环戊=烯基)稀土甲基化物与二苯胺进行交换反应制得了[Li(THF)_4][Cp_2Sm(NPh_2)_2],并测定了相应配合物镥的结构。但是,到目前为止,类似的轻稀土配合物尚未报道。这里,我们以双(叔丁基环戊二烯基)氯化钛为前体,与等当量的二苯胺基锂反应,制得了阴离子型配合物[Li(DME)_3][(t—BUCP)_2Nd(NPh_2)_2]·1/2DME,并测定了其单晶结构。
In 1990, Schumann, H. et al. Reported that [Li (THF) _4] [Cp_2Sm (NPh_2) _2] was prepared by the exchange reaction of bis (cyclopentadienyl) rare earth methylate with diphenylamine and the corresponding Structure of complex 镥. However, so far, similar light rare earth complexes have not been reported. Here, we use bis (tert-butylcyclopentadienyl) titanium chloride as a precursor and react with an equivalent amount of lithiumdianiline to prepare an anionic complex [Li (DME) 3] [(t-BUCP) (NPh_2) _2] · 1 / 2DME, and its single crystal structure was measured.
