(equation presented) The reversible nature of the imine bond formation in CDCl3 solution has been exploited to exchange substituted for unsubstituted m-phenylenediamine (MPD) units in hemicarcerand octaimines. Moreover, acid-catalyzed imine exchange has been shown to provide a novel mechanism whereby ferrocene (Fc) can be released as an entrapped guest from the hemicarceplex C2B4⊙Fc dissolved in CDCl3 to give the hemicarcerand C2B4 when excess of both MPD and trifluoroacetic acid are present.
