Özet

Three novel fully substituted urea derivative cyclotriphosphazene compounds 5-7 were synthesized by alkyne-azide 1,3-dipolar cycloaddition reaction of propargyl substituted ureas 2-4 with hexaazide substituted cyclotriphosphazene 1 in the presence of Cu(I) catalyst. All compounds were characterized with spectroscopic techniques such as FT-IR, H-1, C-13, and P-31 nuclear magnetic resonance and mass spectroscopy. Also, the usefulness of compounds 5-7 as anion carriers was investigated by H-1 NMR spectroscopy. For this purpose, H-1 NMR spectra of compounds 5-7 were recorded in the presence of tetrabutylammonium fluoride in DMSO-d(6). It was determined, that the urea protons in the compounds interact with fluoride.
