    Description / Table of Contents: Fluorine Exchange Reactions in Metal Trifluorophosphine Complexes, VIII. synthesis and Reactions of Nickel(0) Complexes of the Ligand [Bis(trimethylsilyl)amino]difluorophosphineNi(PF3)4 does not react with NH(SiMe3)2, but it does react with the sodium salt of the latter (3); the fluorine exchange reactions produce Ni(PF3)3{PF2N(SiMe3)2} (4) and Ni(PF3)2{PF2N(SiMe3)2}2 (5). The free ligand PF2N(SiMe3)2 is readily accessible by thermolysis of 5. Treatment of 4 with water or diphenylchlorophosphine leads to the formation of the nickel(0) complexes Ni(PF3)3(PF2NHSiMe3), Ni(PF3)3(PF2NH2), and Ni(PF3(PClPh2){PF2N(PPh2)2}. The mechanism of the N—Si cleavage is discussed.
    Notes: F-Substitutionsreaktionen an Ni(PF3)4 finden nicht mit NH(SiMe3)2, wohl aber mit seinem Natriumsalz 3 statt, wobei Ni(PF3)3{PF2N(SiMe3)2} (4) und Ni(PF3)2{PF2N(SiMe3)2}2 (5) anfallen. Die Thermolyse von 5 macht den freien Liganden PF2N(SiMe3)2 leicht zugänglich. Mit Wasser und Diphenylchlorphosphin erhält man aus 4 die Komplexe Ni(PF3)3 )(PF2NHSiMe3), Ni(PF3)3(PF2NH2) und Ni(PF3)2(PClPh2){PF2N(PPh2)2}. Die Mechanismen der N—Si-Spaltungsreaktionen werden diskutiert.
