文摘

The reaction of the N,N-spiro bridged octachlorobis(cyclotriphosphazene), {N3P3Cl4[br-N(CH2)5CH3]2N3P3Cl4} (1), in three stoichiometries (1:0.7, 1:2 and 1:4) with the disodium salt of 1,3-propanediol in THF at room temperature produced seven products, whose structures have been characterized by elemental analysis, mass spectrometry, 1H and 31P NMR spectroscopy; also the crystal structures of 6 and 8 were determined by X-ray crystallography. The reactions gave a mixture of rearranged derivatives (2, 4 and 5) in which the central four membered cyclophosphazane ring transformed into a six-membered monocyclophosphazene ring, as well as the normal substituted derivatives (3, 6–8). In addition, the results of all the reactions were compared with previous work on the reactions of the starting compound 1 with the disodium derivative of 1,2-ethanediol, in the same mole ratios and in the same solvent, THF.
