二茂镱羧酸衍生物的合成
Synthesis of Dicyclopentadienyl Ytterbium Carboxylate Derivatives
【摘要】 本文报道了四种新的二茂镱羧酸衍生物的合成:Cp2YbOCOC(CH3)3(1),Cp2YbOCOCCl3,(2),Cp2YbOCOCH2CH3(3),Cp2YbOCOCH2Cl(4)。这些络合物都经元素分折、红外光谱及质谱鉴定。可能由于这些络合物具有桥式二聚体结构,因而增强了它们对空气的稳定性。
【Abstract】 Four new dicyclopentadienyl ytterbium carboxylate derivatives,namely,Cp2YbOCOC(CH3)3(1),Cp2YbOCOCCl3(2),Cp2YbOCOCH2CH3(3),Cp2YbOCOCH2Cl(4),were synthesized.These complexes were identified by elemental analysis,IR andMS.The higher stability of these complexes in air may be due to their bridged dimer struc-tures.
