Metallorganische lewis-säuren: XXVI. Nachweis des dynamischen verhaltens des koordinierten tetrafluoroborat-liganden in Cp(OC)2(R3P)MoFBF3 mittels 19F-NMR-spektroskopie

Zusammenfassung The coordination of the tetrafluoroborate ligand in Cp(OC) 2 (R 3 P)MoFBF 3 (R = Me, Et) is confirmed by a 19 F NMR study (at −80°C), the spectrum shows a double quartet for the metal-coordinated fluorine atom and a doublet for the terminal fluorine atoms. The 19 F NMR spectrum of Cp(OC) 2 (Me 3 P)MoFBF 3 shows equivalent fluorine atoms at room temperature.
