Abstract
Acyclic polyethers (7) (containing a ferrocene nucleus in both terminal sites) were synthesized by a one-pot reaction of 1,1′-diacetoxyferrocene with halide. Also, ferrocene derivatives (11) 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 7, suggesting the complexing of 7 with cations. However, a similar spectral change could not be observed in 11. 7a extracts silver and thallium ions most effectively, the extraction efficiency of several metal cations being in this order: Ag+>Tl+>Cs+>K+>Li+>Na+.This publication has 4 references indexed in Scilit:
