Abstract
The reaction of hexabromocyclotriphosphazene, N3P3Br6 with ethylamine yields the derivatives N3P3Br6-n(NHEt)n [n = 1, 2(two isomers), 4 and 6]. Two hydrogen bromide adducts, N3P3Br2(NHEt)4·HBr and N3P3(NHEt)6·HBr have also been isolated. The 1H NMR data indicate that the bis-derivatives have nongeminal structures whereas the tetrakis-compound possesses a geminal structure. For the hydrogen bromide adducts, infrared and 1H NMR spectroscopic data suggest that protonation occurs at a ring nitrogen atom. The halogen replacement pattern is very similar to that observed in the analogous reaction of hexachlorocyclotriphosphazene, N3P3Cl6.
