摘　　要：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 the paper,syntheses of the bridged cyclopentadienyl rare earths complexes（C5H4CH2CH2C5H4）LnCl·THF（Ln=Nd,Gd,Yb） were investigated.First,cyclopentadienylsodium reacted with BrCH2CH2Br to form bridged cyclopentadiene;second,bridged cyclopentadiene reacted with Sodium in the solvent THF to give bridged cyclopentadienylsodium;finally,the title complexes（C5H4CH2CH2C5H4）LnCl·THF（Ln=Nd,Gd,Yb） were prepared by the reaction of anhydrous LnCl3（Ln=Nd,Gd,Yb） with bridged cyclopentadienylsodium in the molar ratio of 1/1 in THF,the complexes were characterized by elemental analysis and infrared spectroscopy.
