• 論文の詳細を見る

• Acyclic polyethers (<B>7</B>) (containing a ferrocene nucleus in both terminal sites) were synthesized by a one-pot reaction of 1,1′-diacetoxyferrocene with halide. Also, ferrocene derivatives (<B>11</B>) having polyethylene glycols were synthesized by the reaction of potassium salt of hydroxyferrocene with dihalide in DMF. On the addition of alkali metal thiocyanate in methanol, a hypsochromic shift and an increasing intensity of the absorption band at 438 nm were observed in ferrocene-containing polyethers <B>7</B>, suggesting the complexing of <B>7</B> with cations. However, a similar spectral change could not be observed in <B>11</B>. <B>7a</B> extracts silver and thallium ions most effectively, the extraction efficiency of several metal cations being in this order: Ag<SUP>+</SUP>>Tl<SUP>+</SUP>>Cs<SUP>+</SUP>>K<SUP>+</SUP>>Li<SUP>+</SUP>>Na<SUP>+</SUP>.
