| Abstract: | Trivalent-Pentavalent Phosphorus Compounds/Phosphazenes. IV. Preparation and Properties of New N-silylated Diphosphazenes Phosphazeno-phosphanes, R3P = N? P(OR′) 2 (R = CH3, N(CH3)2; R′ = CH2? CF3) react with trimethylazido silane to give N-silylated diphosphazenes, R3P = N? P(OR′)2 = N? Si(CH3)3 compounds decompose by atmospherical air to phosphazeno-phosphonamidic acid esters, R3 P?N? P(O)(O? CH2? CF3)(NH2). Thermolysis of diphosphazene R3P = N? P(OR′) 2 = N? Si(CH3)3 (R = CH3, R′ = CH2? CF3) produces phosphazenyl-phosphazenes [N?P(N?P(CH3)3)OR′] n. The compounds are characterized by elementary analysis, IR-, 1H-, 29Si-, 31P-n.m.r., and mass spectroscopy. |
