| Summary: | Reactions of hexachlorocyclotriphosphazatriene,N3P3Cl6 (1)with 1-amino-2-propanol (2), in(1:1:2, 1:2:4 and 1:3:6) mole ratios, in excess of NaH, in THF and acetonitril solutionsyield a total of 6 novel products:onemono-open chain, N3P3Cl5[HN-CH2-CH(CH3)-OH](3); one monospiro, N3P3Cl4[O-CH(CH3)-CH2-NH](4); one trans bis-open chain, N3P3Cl4[HN-CH2CH(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 haveinteresting structural aspects as well as physical properties. Their structureswere established by elemental analysis, TL-MS, 31P and 1HNMR spectral data. Stability constants were determinedusing a simple potentiometric titration. For evaluation of melting behaviorand purity of derivatives (7) and (8), thermal transition peaks and theircorresponding enthalpies were determined via DSC technique. Spectroscopicdata, product types and relativeyields are compared with those of the previously investigated derivatives of N3P3Cl6(1) with aliphatic difunctional reagents. |
