(Chemical Equation Presented) N-(p-Dimethylamino)benzoyl-N′- phenylthiourea as an N-acylthiourea is known to be unable to bind anions due to a strong intramolecular hydrogen bond (IHB). We show here that by inserting an amido group in the N′-phenyl side the newly designed N-benzamido-N′- benzoylthioureas, despite this IHB too, bind strongly to anions with binding constants on the order of 106-107 mol-1 L. Results suggest that potential anion receptors or organocatalysts could be developed on the basis of this framework with a wide structural diversity.
