Abstract
The fluorophosphanes Ph2PF (1), PhOPF2 (2), C5H10NPF2 (3), (Et2N)PF2(4 ), and (Et2N)2PF (5) react with Me3SiN3 via azidophosphanes R3-nP(N3)n to oligo- and polyphosphazenes, (RR'P = N)n. (iPr2N)2PF (6), however, is oxidized by Me3SiN3 yielding the N-silylated phosphazene (iPr2N)2P F = N-SiMe3 (7). tBuPh2SiN3 is considerably less reactive. On contrary to Me3SiN3 it even oxidizes 5 and 1 forming (Et2N)2FP = N-SiPh2tBu (1 0) and Ph2FP = N-SiPh2tBu, resp.
