Ferrocene cryptand molecules

A number of ferrocene cryptand molecules (66-74) ((29)—(31)) have been reported in the literature and it is only relatively recently that their electrochemical coordination properties have been disclosed. We have synthesized potassium-selective metallocene cryptands (72) (30) and (31) the electrochemistry of the former in the presence of K+ guest cations proved disappointingly irreversible (75). Hall and co-workers (76) have used cyclic voltammetry to investigate the coordination of... 

A large number of ferrocene cryptand-type molecules have been reported in the literature in the last ten years. Hall and co-workers, the initial pioneers of these cryptand systems (Beer etal., 1984 Bell and Hall, 1980 Hammond etal., 1986 Bell etal., 1983 Hall and Sharpe, 1990,1991 Hall etal., 1990a,b, 1991a,b,...
