| Abstract: | N-Diphenylphosphino-triphenylphosphazene possesses a highly reactive (C6H5)2P group. At room temperature CH3J adds to give (C6H5)3P?N?P(C6H5)2CH 3J whilst phenylbromide did not react under similar conditions. The phosphorous halides (C6H5)2PX(X = Cl, Br)add in a 1:1 mole ratio to yield (C6H5)3P?N?P(C6H5)2? PC6H5)2X; this addition is also the preferred reaction with C6H5PCl2, but PCl3 is in part dehalogenated by (C6H5)3P?N? P(C6H5)2, and PSCl3 desulfurized. The chalcogens O, S, Se, Te readily add to the P(III) atom of the base and this is also the case with BH3. CS2 forms the betaine (C6H5)3 · · P?N? P(C6H5)2? C(S)S. The IR and NMR spectra of the new compounds are discussed. |
