Reactions of cyclochlorotriphosphazatriene with 1-amino-2-propanol. Calorimetric and spectroscopic investigations of the derived products.

Reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6 (1) with 1-amino-2-propanol (2), in (1:1, 1:2 and 1:3) mole ratios, in excess of NaH, in THF and acetonitril solutions yield a total of 6 novel products: one mono-open chain, N3P3Cl5[HN-CH2-CH(CH3)-OH] (3); one monospiro, N3P3Cl4[O-CH(CH3)-CH2-NH] (4); one trans bis-open chain, N3P3Cl4[HNCH2CH( CH3)-OH]2 (5); one dispiro, N3P3Cl2[O-HC(CH3)-CH2-NH]2 (7); one tri-open chain, N3P3Cl3[HN-CH2CH(CH3)-OH]3 (6); and one tri-spiro, N3P3[O-HC(CH3)-CH2-NH]3(8) derivatives. These compounds have interesting structural aspects as well as physical properties. Their structures were established by elemental analysis, TL-MS, 31P and 1H NMR spectral data. Stability constants were determined using a simple potentiometric titration. For evaluation of melting behavior and purity of derivatives (7) and (8), thermal transition peaks and their corresponding enthalpies were determined via DSC technique. Spectroscopic data, product types and relative yields are compared with those of the previously investigated derivatives of N3P3Cl6 (1) with aliphatic difunctional reagents.
