The compound reacts with HSCH2(CH2OCH2)3CH2SH in the presence of base giving the metalla-crown ether complex which can undergo a reversible one-electron oxidation.Treatment of (M=Mo or W) with 4'-carboxybenzo-15-crown-5 and base gives the complexes 2>, which also undergo reversible oxidation.Small changes in the E1/2 (2> (M=Mo or W) prepared from the sodium salt of (benzo-15-crown-5) -4'-thiol and , undergo a reversible one-electron oxidation and the E1/2 is shifted anodically upon addition of alkali metal cations.

A general high-yielding method for the preparation of monosubstituted β-cyclodextrin derivatives which have attached a thiol group in position 6 is described. The thiol group is attached through linkers of different lengths and repeating units (ethylene glycol or methylene). The target compounds were characterized by IR, MS and NMR spectra. A simple method for their complete conversion to the corresponding disulfides as well as a method for the reduction of the disulfides back to the thiols is presented. Both, thiols and disulfides are derivatives usable for well-defined covalent attachment of cyclodextrin to gold or polydopamine-coated solid surfaces.
