Fluorine Exchange in Trifluorophosphine Metal Complexes. IX1. (Reactions of Tetrakis(trifluorophosphine)nickel(0) with Alkyl(trimethylsilyl)amines and Amides2)Alkylaminodifluorophosphine complexes Ni(PF3)4-n(PF2NHR)n (n = 1, 2, 3) 8-11 and Me3SiF are obtained, if alkyl(trimethylsilyl)amines NHR(SiMe3) (R=CH3 and n-C4H9) are reacted with Ni(PF3)4 (1). The mechanism of these peripheric reactions is discussed by assuming a four centered type intermediate. However reactions of 1 with the lithium amides LiNR(SiMe3) (R = CH3, C2H5, n-C4H9, and C6H5) yield LiF and the difluorotrimethylsilylaminophosphine complexes Ni(PF3)4-n[PF2NR(SiMe3)]n (n = 1, 3, 4) 12-18.
Notes:
Ni(PF3)4 (1) reagiert mit Alkyl(trimethylsilyl)aminen NHR(SiMe3) (R=CH3 und n-C4H9) unter Me3SiF-Abspaltung zu den Alkylaminodifluorphosphinkomplexen Ni(PF3)4-n(PF2NHR)n (n = 1, 2 und 3) 8-11. Der Reaktionsablauf wird anhand eines Vierzentren-Synchron-Mechanismus diskutiert. Hingegen liefern die Lithiumamide LiNR(SiMe3) (R=CH3, C2H5, n-C4H9 und C6H5) mit 1 unter LiF-Abspaltung die Organyl(trimethylsilyl)-aminodifluorphosphinkomplexe Ni(PF3)4-n[PF2NR(SiMe3)]n (n = 1, 3 und 4) 12-18.
