    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.

    Description / Table of Contents: On the Reaction of Halomethylphosphonium Halides, [R3PCYnX3-n]X, with Phosphanes, R′3PThe results of the reaction of 19 different halomethylphosphonium halides, [R3PCYnX3-n]X (R = Ph, n-Bu, Me2N, Et2N; Y = H, F; X = Cl, Br, I; n = 0-2), with Ph3P, n-Bu3P, and (R2N)3P are presented. As reaction products bisphosphonium salts, [R3P—CYnX2-n—PR′3]X2, and phosphoranylphosphonium salts, [R3P=CY—PR′3]X, or reduced (halo)methyl-phosphonium salts, [R3PCHYnX2-n]X, are obtained. [Ph3PCBrF2]Br and [Bu3PCBrF2]Br react with R′3P by trans-alkylation forming [R′3PCBrF2]Br. The factors influencing the course of the reaction are discussed.
    Notes: Es wird über die Reaktion von 19 verschiedenen Halomethylphosphoniumsalzen, [R3PCYnX3-n]X (R = Ph, n-Bu, Me2N, Et2N; Y = H, F; X = Cl, Br, I; n = 0-2), mit Ph3P, n-Bu3P und (R2N)3P berichtet. Als Reaktionsprodukte werden Bisphosphoniumsalze, [R3P—CYnX2-n—PR′3]X2, und Phosphoranylphosphoniumsalze, [R3P=CY—PR′3]X, oder reduzierte (Halo)methylphosphoniumsalze, [R3PCHYnX2-n]X, erhalten. [Ph3PCBrF2]Br und [Bu3PCBrF2]Br reagieren mit R′3P unter Umalkylierung zu [R′3PCBrF2]Br. Die den Reaktionsverlauf beeinflussenden Faktoren werden diskutiert.
