    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.
