环辛四烯与烷氧基混配稀土金属有机化合物的合成

Synthesis of organolanthanides containing cyclooctatetraenyl and alkoxyl

<正> 本研究合成了四种稀土金属络合物[(C_8H_8)Ln(μ—OR)(THF)]_2(Ln=Y,Lu)。经过分离,在-30℃培养均得晶体。经元素分析,~1H核磁共振,~13C核磁共振和质谱对络合物的鉴定,确认这是一类半夹心氧桥联双核络合物,有关晶体结构的X—衍射分析,进一步证明了这种结构。 1.[(C_8H_8)Y(μ—OC_6H_5)(THF)]_2为无色直角六面长方形晶体,m.p.325℃(分解)。

Four new organolanthanides of [(C8H8)Ln(μ-OR)(THF)]2(R=Ph,C6H3Me2-2. 8)(Ln=Y, Lu) were prepared respectively. These compounds were identified by elemental analysis,1H-NMR , 13C-NMR and MS(mass spectra)
