The synthesis of methylated calix[4](aza)crowns and their complexing properties towards Co 2+ , Ni 2+ and Cu 2+ are described. The crystal structure of one of those ligands, hydrogen bonded to a picric acid molecule via a water molecule, is given.
The acid-catalyzed (with HCl) condensation reactions of resorcinol ( ) with 1-naphthaldehyde (2) and isobutyraldehyde (3) furnished the tetrameric macrocyclic compounds 4 and 6. Detailed NMR-investigations of the acetylated tetrameric species 5 surprisingly support a structure not in agreement with
