文章研究了新型二甲撑桥联茂基稀土氯化物的合成,首先通过环戊二烯钠与1,2-二溴乙烷在四氢呋喃中发生反应形成二甲撑桥联环戊二烯,随后二甲撑桥联环戊二烯与金属钠作用使其转化成二甲撑桥联环戊二烯二钠盐,无水三氯化稀土LnCl3(Ln=Nd,Gd,Yb)与二甲撑桥联环戊二烯二钠盐NaC5H4CH2CH2C5H4Na以1∶1摩尔比在四氢呋喃溶液中反应得到新型二甲撑桥联环戊二烯基稀土氯化物(C5H4CH2CH2C5H4)LnCl.THF(Ln=Nd,Gd,Yb),产物经元素分析和红外分析的表。
In this paper, the synthesis of a novel dimethylene bridged liaoxocarboxylate rare earth chloride was studied. Firstly, dimethylcyclo-cyclopentadiene was formed through the reaction of sodium cyclopentadienyl and 1,2-dibromoethane in tetrahydrofuran, Methylene bridged the reaction of cyclopentadiene and sodium metal to convert it to dimethyl bridged cyclopentadiene disodium salt, anhydrous trichloride rare earth LnCl3 (Ln = Nd, Gd, Yb) The cyclopentadienyl disodium salt NaC5H4CH2CH2C5H4Na is reacted with 1: 1 molar ratio in tetrahydrofuran solution to obtain the novel dimethylene bridged cyclopentadienyl rare earth chloride (C5H4CH2CH2C5H4) LnCl.THF (Ln = Nd, Gd, Yb) , The product by elemental analysis and infrared analysis of the table.
