Reaction of gem-diphenyltetrafluorophosphazene, [1,1-(C6H5)(2)]P3N3F4 (1) with LiO(CH2)(3)OLi resulted in the formation of four products, spiro-3,3-[O(CH2)(3)O]}[1,1-(C6H5)(2)]P3N3F2 (2), ansa-3,5-[O(CH2)(3)O]}[1,1-(C6H5)(2)P3N3F2] (3), bridged-[1,1-(C6H5)(2)N3P3F3][O(CH2)(3)O] [1,1-(C6H5)(2)N3P3F3] (4) and dangling-[HO(CH2)(3)O][1,1-(C6H5)(2)P3N3F3] (5) derivatives of 1, among which compound 5 was found to be the major product. Reaction of 1 with the dilithiated ferrocene derived diol, FcCH(2)P(S)(CH2OLi)(2) resulted in the formation of two isomers of ansa substituted fluorophosphazenes namely endo-[1,1-(C6H5)(2)]3,5-[FcCH(2)P(S)(CH2O)(2)]}P3N3F2 (6) and exo-[1,1-(C6H5)(2)]3,5-[FcCH(2)P(S)(CH2O)(2)]}P3N3F2 (7). These were formed along with the spiro isomer [1,1-(C6H5)(2)]3,3-[FcCH(2)P(S)(CH2O)(2)]}P3N3F2 (8) the dangling derivative [1,1-(C6H5)(2)P3N3F3][OCH2(FcCH(2))P(S)CH2OH] (9) and the bridged compound [1,1-(C6H5)(2)P3N3F3][OCH2(FcCH(2))P(S)CH2O][1,1-(C6H5)(2)P3N3F3] (10). All compounds were separated by column chromatography and characterized by H-1, P-31H-1}, F-19 NMR, mass spectra and elemental analysis. The spirocyclic compound 8 was also characterized by X-ray crystallography. (c) 2006 Elsevier B.V. All rights reserved.
