The synthesis of 13 new macrocyclic polyether-diester ligands containing the furan, 3,4-dimethoxyfuran, tetrahydrofuran, and thiophene subcyclic by the reaction of a diacid dichloride with the appropriate glycol is described. The complexation properties of these ligands with alkylammonium and metal cations were determined and compared with the crown ethers. The free energies of activation (..delta

Tetrahydrofuran-(THF)-2,5-dicarbaldehyde and a process of preparing the same are described. The process involves reacting THF-diols in an inert organic solvent with an oxidizing agent at a temperature up to about 50C. The process can use either HMF or THF-diols as starting materials, and enables a single-step conversion of THF-diols into a precursor material that can be transformed into a multitude of furanic derivative compounds. THF dicarbaldehyde can be modified according to certain reaction processes to generate either new or existing derivative compounds.
