Cyclopentadienyliron carbonyl

There are many substituted 77-cyclopentadienyliron carbonyl cations, which are often prepared from a 7r-cyclopentadienyliron dicarbonyl halide. The halide may be expelled by a variety of ligands to form a cation in preference to carbonyl displacement. Which actually occurs in practice appears to be a function of the reaction parameters, such as reaction temperature, basicity of the ligand, and halide used. The cations of this type are listed in Table III. 

I hc reaction of some 7r-cyclopentadienyliron carbonyl cations with Nal H4 (62), phenyl- and perfluorophenyllithium (232, 233) have been studied. 

A stable polynuclear paramagnetic 7r-cyclopentadienyliron carbonyl bromide [CpFe(CO)]4+Br3 is reported to be formed by oxidation of the tetrameric carbonyl [CpFe(CO)]4 (160). 

Lewis et al. (131) have measured spectra of some tin and mercury derivatives of cyclopentadienyliron carbonyl (XCVII)-(XCIX).
