| dc.description | The rates of the reactions of hexachlorocyclotriphosphazene (N3P3Cl6) and octachlorocyclotetraphosphazene (N4P4Cl8) with t-butylamine in methyl cyanide were determined at three temperatures in the range 273â 308 K. The reaction of N3P3Cl6 was also studied in tetrahydrofuran. Rigorous purification of the chlorophosphazenes and the solvents was essential to obtain reproducible results. An S N2(P) mechanism involving the formation of a five-co-ordinate phosphorus intermediate is in accord with the kinetic data. The greater reactivity of N4P4Cl8 compared to that of N3P3Cl6 arises entirely from the lowering of the enthalpy of activation. The effects of ring size and the solvent on the rates are discussed in terms of the activation parameters. |
