Phosphorus containing macrocycles on the basis of 2,7-dihydroxynaphthalene and amides of phosphorous acid were synthesized. The molecular assembly technique for the preparation of “uniform” naphthaphosphacyclophanes (containing only residues of 2,7-dihydroxynaphtalene) and “nonuniform” naphthaphosphacyclophanes (containing different naphthylene residues with hydroxy groups located in different aromatic rings) is proposed. Their properties were studied and the computer MM2 optimizations of molecular geometry were carried out. A method for the preparation of phosphorus containing macrocycles with three or four regularly exchanging 2,7-dihydroxynaphtylene and phosphorus acid residues was proposed. Their oxidation and sulfur addition were also studied. Individual character and structure of all synthesized systems were proved unambiguously by TLC, 31P, 13C and 1H NMR spectroscopy, elemental analysis and MALDI-TOF mass-spectrometry.

 

Keywords: 2,7-Dihydroxynaphthalene, triamidophosphites, molecular assembly, macroheterocycles, naphthaphosphacyclophanes, phosphocrown ethers.
