Phosphorus–nitrogen compounds. Part XXXI. Reactions of hexachlorocyclotriphosphazatriene with aniline

Hexachlorocyclotriphosphazatriene reacts with aniline to give mono, 2,2-bis-, 2,4-bis-, 2,2,4-tris-, 2,2,4,4-tetrakis-, and hexakis-anilino-derivatives, N3P3Cl6 –n(NHPh)n(n= 1, 2, 2, 3, 4, or 6). The predominantly geminal reaction pattern was established by basicity measurements, and by the preparation of anilinodimethylaminocyclotriphosphazatrienes, and measurements of their 1H n.m.r. spectra.
