SYNTHESE UND SPEKTROSKOPISCHE CHARAKTERISIERUNG VON CYCLOPENTADIENYLEISEN-KOMPLEXEN MIT P-N-LIGANDEN DES TYPS (C6H5)3-nP(NR2)N (n = 0-3; R = CH3, C2H5)

The complex cations BF4 (L = (C6H5)_3-nP(NR2)_n; n = 0-3; R = CH3, C2H5) have been obtained from the reaction of BF4 (I) with L.The reaction of I with E(NR2)3 (E = As, Sb; R = CH3) is also described.Spectroscopic investigations (IR, 1H, 13C and 31P NMR) indicate an increase in electron density on the iron center through increase of the number of P-bound NR2 groups.
