    Description / Table of Contents: Fluoridolysis of N-Phosphoryl PhosphazenesIn the reaction of the N-phosphoryl phosphazenes X3P=N—P(Y)X2 (X = Cl, PhO, Et2N, CF3CH2O, PrS, Ph; Y = O, S) (1-18) with Et3N · nHF (n ≍ 3 or 0.6) fluoro derivatives of N-phosphoryl phosphazenes (see table 2) as well as N-phosphorylated imiddotetrafluorophosphates, [F4P=N—P(Y)Cl2]- (Y = O, S), and imidopentafluorophosphates, [F5P—N—P(Y)X2]2- or [F5P—NH—P(O)X2]- (see table 3), are formed. t-BuNHPCl2=N—POCl2 reacts in acetonitrile with Et3N or i-Pr2EtN to form a product, representing probably the diazadiphosphetine (5 b).
    Notes: Bei der Umsetzung der N-Phosphorylphosphazene X3P=N—P(Y)X2 (X = Cl, PhO, Et2N, CF3CH2O, PrS, Ph; Y = O, S) (1-18) mit Et3N · nHF (n ≍ 3 oder 0,6) werden durch den Austausch von Chlor sowie PhO-, Et2N- und CF3CH2O-Gruppen gegen Fluor Fluorderivate von N-Phosphorylphosphazenen (siehe Tab. 2) sowie N-phosphorylierte Imiddotetra- und -pentafluorophosphate, [F4P=N—P(Y)Cl2]- (Y = O, S) und [F5P—N—P(Y)X2]2- bzw. [F5P—NH—P(O)X2]- (siehe Tab. 3) gebildet. t-BuNHPCl2=N—POCl2 reagiert in Acetonitril mit Et3N oder i-Pr2EtN zu einem Produkt, bei dem es sich höchstwahrscheinlich um das Diazadiphosphetin (5 b) handelt.

    Description / Table of Contents: Fluoridolysis of Diphosphoryl CompoundsThe behaviour of diphosphoryl compounds [X2(O)P]2Y in fluoridolysis reactions is decisively determined by the nature of the bridging group Y. In the cases of Y = NH and CH2 and X = Cl [F2P(O)]2N- and [F2P(O)]2CH2 are obtained quantitatively. For Y = NPh, O, and CH2 the formation of phosphorylated pentafluorophosphates [F5P—Y—POX2]- is observed. Amido and ester derivatives containing fluorine (see table 2) are obtained from the corresponding chloro compounds by Cl/F exchange. Fluoridolysis of the azadiphosphetidine 19 results in the formation of acyclic 19 a.
    Notes: Das Fluoridolyseverhalten von Diphosphorylverbindungen [X2(O)P]2Y wird maßgeblich durch die Brückengruppe Y bestimmt. Im Falle von Y = NH und CH2 sowie X = Cl werden quantitativ [F2P(O)]2N- und [F2P(O)]2CH2 erhalten. Für Y = NPh, O und CH2 wird die Bildung von phosphorylierten Pentafluorophosphaten [F5P—Y—POX2]- beobachtet. Aus chlorhaltigen Amido- und Esterderivaten werden durch Chlor-Fluor-Austausch die entsprechenden Fluorderivate erhalten (siehe Tab. 2). Die Fluoridolyse des Azadiphosphetidins 19 ergibt die acyclische Verbindung 19 a.

    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.
