    Description / Table of Contents: On the Reaction of Fluorophosphanes with Silylazides.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)2PF=N—SiMe3 (7). tBuPh2SiN3 is considerably less reactive. On contrary to Me3SiN3 it even oxidizes 5 and 1 forming (Et2N)2FP=N—SiPh2tBu (10) and Ph2FP=N—SiPh2tBu, resp.
    Notes: Die Fluorphosphane Ph2PF (1), PhOPF2 (2), C5H10NPF2 (3), (Et2N)PF2 (4) und (Et2N)2PF (5) reagieren mit Me3SiN3 über die Zwischenstufe der Azidophosphane R3-nP(N3)n zu Oligo- und Polyphosphazenen, (RR′P=N)n. (iPr2N)2PF (6) wird dagegen durch Me3SiN3 zum N-silylierten Phosphazen (iPr2N)2PF=N—SiMe3 (7) oxidiert. tBuPh2SiN3 ist wesentlich weniger reaktiv. Im Gegensatz zu Me3SiN3 oxidiert es aber auch 5 und 1 zu (Et2N)2FP=N—SiPh2tBu (10) bzw. Ph2FP=N—SiPh2tBu.
