Abstract
The reactions of trimericphosphazenes with sodium [2, 2â²-methylenebis(4-chlorophenoxide)] have been investigated. Experimental studies were carried out in argon atmosphere. The sodium aryloxides were prepared from methylenebis (4-chlorophenol) and sodium. The phosphazene and phenolate were reacted at â20 °C and then refluxed. After the reaction products (1 and 2) were separated by column chromatography, the structures of the compounds were characterized by elemental analysis, IR, 1H-, 13C-, 31P-NMR, and mass spectroscopy. The compound 1 (spiro) crystallizes in the monoclinic space group Cm with unit cell parameters: a=8.231(1), b=16.242(2), c=7.731(1) Ã
, β=103.31(1)°, V=1005.8(2) Ã
3, Dx=1.796Â g cmâ3 respectively. The crystal structures were solved by direct methods and refined by full-matrix least squares.
