    Description / Table of Contents: A simple Synthesis of Fluoro(organyl)PhosphanesA simple synthesis of fluoro(organyl)phosphanes, RPF2, and R2PF, which is based on the reaction of the corresponding chloro compounds with triethylamine-HF adducts in the presence of free triethylamine, is presented. The method even allows the synthesis of compounds of extremely low stability.
    Notes: Es wird ein einfaches Verfahren zur Synthese von Organyldifluor-und Diorganylfluorphosphanen, RPF2 und R2PF, vorgestellt, das auf der Umsetzung der entsprechenden Chlorverbindungen mit Triethylamin-HF-Addukten in Gegenwart von freiem Triethylamin beruht und auch die Synthese sehr wenig stabiler Vertreter dieser Substanzklasse erlaubt.

    Topics: Chemistry and Pharmacology
    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.
