Özet
In this study, N,N-spiro cyclotriphosphazene derivatives (1a-4a) with one stereogenic center were synthesized in two steps. Firstly; mono substituted phosphazene compounds [N3P3Cl5NHC6H5 (1), N3P3Cl5OC5H4N (2), N3P3Cl5OC6H2-Me-2,4,6 (3), N3P3Cl5OC6H2-Bu-t-2-Me-4 (4)] were prepared. Secondly, these compounds (1-4) were allowed to react with symmetrical difunctional reagent N,N '-diisopropylpropane-1,3-diamine to obtain cyclotriphosphazenes having one stereogenic center. The reaction of N3P3Cl5XAr (1-4) with N,N '-diisopropylpropane-1,3-diamine was carried out in dichloromethane. Four new N,N-spiro phosphazene compounds (1a-4a) which have one stereogenic center were obtained from these reactions. The structures of these compounds were characterized by H-1, C-13 and P-31 NMR spectrometry and elemental analyses.
