Abstract: | Reactions of reactive cyclopentadienyliron complexes C5H5Fe(CO)2I, C5H5Fe(CO)2THF]BF4, C5H5Fe(CO)((CH3)2S)2]BF4 and C5H5Fe(p-(CH3)2C6H4)]PF6 with P(OR)3 as ligands (R = CH3, C2H5, i-C3H7 and C6H5) lead to the formation of the complex compounds C5H5Fe(CO)2?n(P(OR)3)nI and C5H5Fe(CO)3?n(P(OR)3)n]X (n = 1, 2 and n = 1–3, X = BF4, PF6). Spectroscopic investigations (IR, 1H, 13C and 31P NMR) indicate an increase of electron density on the central metal with increasing substitution of CO groups by P(OR)3 ligands. The stability of the compounds increase in the same way. |
