    Description / Table of Contents: Replacement and Oxidation Reactions of N-Dichlorophosphanyl Triphenylphosphazene, Ph3P=N—PCl2The title compound (1) reacts with MeOH, EtOH, PhOH, EtSH, and water forming N-phosphanyl or N-phosphinoyl phosphazenes, resp., Ph3P=N—PX2 (X = OPh(8), SEt(9)) or Ph3P=N—PH(O)X (X = Cl(3), OH(4), OMe(5), OEt(7)). The reaction of 1 with P(NEt2)3 yields Ph3P=N—P(NEt2)2 (10). Ph3P=N—PF2(11) and Ph3P=N—PH(O)F (12) are obtained by chlorine-fluorine exchange. The N-phosphanyl compounds 1, 8, 9 and 11 are oxidized by NO2 yielding the corresponding N-phosphoryl derivatives, Ph3P=N—P(O)X2 (X = Cl(2), OPh(13), SEt (14), F(15)). The thiophosphoryl compounds, (Ph3P=N—P(S)X2 (X = Cl(16), OPh(17), F(18)) are obtained by oxidizing 1, 8, and 11 with sulfur.
    Notes: Die Titelverbindung (1) reagiert mit den protischen Nucleophilen MeOH, EtOH, PhOH, EtSH und Wasser zu Phosphanyl- bzw. Phosphinoylphosphazenen, Ph3P=N—PX2 (X = OPh (8), SEt (9)) bzw. Ph3P=N—PH(O)X (X = Cl(3), OH(4), OMe(5), OEt(7)). Die Reaktion von 1 mit P(NEt2)3 ergibt Ph3P=N—P(NEt2)2 (10) und durch Chlor-Fluor-Austausch werden Ph3P=N—PF2 (11) und Ph3P=N—PH(O)F (12) erhalten. Die N-Phosphanylverbindungen 1, 8, 9 und 11 werden durch NO2 zu den entsprechenden N-Phosphorylderivaten Ph3P=N—P(O)X2 (X = Cl(2), OPh(13), SEt (14), F(15)) und die Verbindungen 1, 8 und 11 durch Schwefel zu Thiophosphorylverbindungen (Ph3P=N—P(S)X2(X = Cl(16), OPh(17), F(18)) oxydiert.

    Description / Table of Contents: On the Reaction of Trifluorohalomethanes with PhosphanesThe reactions of trifluorohalomethanes CF3X (X = Cl, Br, I) with Ph3P, Bu3P, (Me2N)3P, and (Et2N)3P were investigated. CClF3 does not react. In the reactions of CBrF3 and CF3I with Bu3P in acetonitrile trifluorophosphonium salts, [Bu3PCF3]X (X = Br, I), are formed, whereas gaseous CF3I and Bu3P yield Bu2PCF3. Depending on the reaction conditions the aminophosphanes form either [(R2N)3PX]X (R = Me, Et; X = Br, I) and CF3H or [(R2N)3PCF3]X.
    Notes: Es wird über die Reaktionen der Trifluorhalomethane CF3X (X = Cl, Br, I) mit Ph3P, Bu3P, (Me2N)3P und (Et2N)3P berichtet. CClF3 verhält sich inert. CBrF3 und CF3I bilden in Acetonitril mit Bu3P Trifluormethylphosphoniumsalze, [Bu3PCF3]X (X = Br, I), während sich gasförmiges CF3I mit Bu3P zu Bu2PCF3 umsetzt. Die Aminophosphane reagieren in Abhängigkeit von den Reaktionsbedingungen zu [(R2N)3PX]X (R = Me, Et; X = Br, I) und CF3H bzw. [(R2N)3PCF3]X.
