Notes:
Ni(PF3)4 (1) tauscht mit Lithiumorganylen und Grignard-Reagentien Fluor gegen Organyl-Gruppen aus, wobei die Komplexe (10-32) Ni(PF3)4-n(PF2R)n (n = 1, 2 und 3), Ni(PF3)3(PFR2), Ni(PF3)2(PF2R)(PFR2) und Ni(PF3)3(PR3) (R = organ. Rest) gebildet werden. Für den Reaktionsablauf wird ein Vierzentren-Synchron-Mechanismus vorgeschlagen.Fluorine Exchange in Trifluorophosphane Metal Complexes. X. Reactions of Tetrakis(trifluorophosphane)nickel(0) with Metal OrganylsThe fluorine atoms in Ni(PF3)4 (1) can be partially substituted by organyl groups yielding the complexes (10-32) Ni(PF3)4-n(PF2R)n (n = 1, 2 and 3), Ni(PF3)3(PFR2), Ni(PF3)2(PF2R)(PFR2) and Ni(PF3)3(PR3) (R = organyl group). The mechanism of these peripheric reactions is discussed by assuming a four centered type intermediate.
