, p. 47 - 51 (2007/10/03)

Large association constants have been obtained in CDCl3 for carboxylic acids and a xanthone receptor linked to a guanidine. Protonation of the guanidine with carboxylic acids has been studied in DMSO. Association of the guanidine receptor and monochloroacetic acid may be observed in this highly competitive solvent.
