    Fluorine Exchange in Trifltiorophosphinemetal Complexes. IVThe Reaction of Nitrosyltrifluorophosphirie Complexes of Iron and Cobalt with Alkoxid- and Hydroxid-IonsFe(NO)2(PF3)2, 1, and Co(NO)(PF3)3, 2, react with alcoxids and phenoxid by a complete F/OR-exchange to the corresponding phosphite complexes Fe(NO)2P(OR)3)2 and Co(NO)(P(OR)3)3, (R = CH3, C2H5, n-C3H7, i-C3H7, n-C4H9, C6H5), 3-13. The nitrosyltrifluorophosphine complexes 1 and 2 change only one or two fluorine atoms against OH--ions to give difluorophosphito complexes: The reaction of 1 with a diisopropylamine/water mixture yields the bis(difluorophosphito) complex [Fe(NO)2(PF2O)2]2-, 15, with 2 under identical conditions [Co(NO)(PF3)2 PF2O]-, 14, is obtained; 1 and 2 react with Ba(OH)2 in THF to give [Fe(NO)2(PF3)PF2O]- resp. 14, the latter reacts under harder conditions partially to [Co(NO)(PF3)(PF2O)2]2-. These difluorophosphito complexes, which are isolated as salts with the cations [(i-C3H7)2NH2]+ and Ba2+, can be alkylated to the corresponding difluorethoxyphosphine derivates of 1 and 2, Fe(NO)2 (PF3)2-n(PF2OC2H5)n (n = 1,2) and Co(NO)(PF3)2PF2OC2H5. All compounds are characterised by IR and mass spectra.
    Notes:
    Fe(NO)2(PF3)2, 1, und Co(NO)(PF3)3, 2, tauschen bei der Umsetzung mit Alkoholaten und Phenolat sämtliche Fluoratome gegen RO-Gruppen aus unter Bildung der entsprechenden Phosphitkomplexe Fe(NO)2(P(OR)3)2 bzw. Co(NO)(P(OR)3)3 (R = CH3, C2H5, n-C3H7, i-C3H7, n-C4H9, C6H5), 3-13. Beide Nitrosyl-trifluorphosphin-Komplexe gehen maximal nur einen zweifachen F/OH-Austausch zu Difluorphosphito-Komplexen ein: In einem Diisopropylamin/Wasser-Gemisch liefert 1 den Bis(difluorphosphito)-Komplex[Fe(NO)2(PF2O)2] 2-, 15, 2 unter gleichen Bedingungen [Co(NO)(PF3)2PF2O- 14; die Umsetzung von 1 und 2 mit Ba(OH)2 in Tetrahydrofuran führt zu [Fe(NO)2(PF3) PF2O]- bzw. 14, welches sich unter drastischen Bedingungen teilweise zu [Co(NO)(PF3) (PF2O)2]2- umsetzt. Diese Difluorphosphito-Komplexe, die als Salze mit den Kationen [(i-C3H7)2NH2]+ bzw. Ba2+ anfallen, können zu den entsprechenden Difluoräthoxy-Derivaten von 1 und 2, Fe(NO)2 (PF3)2-n(PF2OC2H5)n (n = 1, 2) bzw. Co(NO)(PF3)2PF2OC2H5, alkyliert werden. Sämtliche Verbindungen werden anhand der IR- und Massenspektren charakterisiert.
