Notes:
The synthesis and structural characterization of the macrobicyclic ligand 1 containing a reducible hexakis-(phenylthio)benzene electron-acceptor site is described. It is based on the condensation of the tetraoxa-diazamacrocycle 3 with a suitably functionalized derivative 4 of hexakis(phenylthio)benzene. Complexation of a potassium cation by 1 gives the corresponding cryptate 2, with a stability constant of ca. 4000 M-1 as determined by 1H-NMR titration in CD3CN. The reduction potential of the hexakis(phenylthio)benzene electron-acceptor site in 2 is shifted by 170 mV towards more positive values with respect to that in 1 by complexation of potassium.
