An Et2O solution of (SCN)2 was added slowly to a solution of ferrocene to give a dark brown, unidentified powder, which was not a simple thiocyanate, although ferricinium ions were present. Using CH2 Cl2 as solvent a darkcolored crystalline product [(C5H5)2Fe]2Fe(NCS)4 precipitated Ir spectra showed strong bands at 3095, 1414, 1010, and 850 cm.-1 characteristic of the ferricinium ion and at 2055, 480, and 262 cm.-1 due to the iron thiocyanate group. The electronic spectrum in a KBr disk showed a strong maximum at 20.3 kK with a shoulder at 15.8 kK. An analogous reaction between cobaltocene and (SCN)2 in Et2 O at room temperature yielded as the main product yellow crystalline cobalticinium thiocyanate as shown by elemental anal., ir and electronic spectra, conductivity, and proton N.M.R.

WO(X)Fc3 [X = Cl (I), OMe (II), OFc (III), OBu (IV); Fc = ferrocenyl] were obtained by treating WOCl4 with ferrocenyllithium in THF. Reaction of WOCl4 with a threefold excess of FcLi gives I, which may be converted into II using KOMe. Reaction of WOCl4 with a sixfold excess of FcLi gives a mixture containing III and IV in addition to ferrocene and biferrocene. According to the x-ray crystallog. anal., III has a trigonal-bipyramidal structure with three ferrocenyl ligands occupying the equatorial positions and an axial ferrocenoxy group coordinated trans to the oxo ligand. The three W-C(ferrocenyl) (average 2.092 Å) and the O-C(ferrocenyl) [1.33(1) Å] bond distances are remarkably short. The axial tungsten-oxygen distances correspond to a W:O double and a W-O single bond, resp. The 1H and 13C NMR spectra of III are temperature dependent because of a hindered rotation of the ferrocenyl ligands around the W-C(ferrocenyl) bonds.

Application In Synthesis of Bromoferrocene. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Synthesis, X-ray structure and chemical properties of 17α-ferrocenylestradiol.

The X-ray structure of 17α-ferrocenylestradiol shows that the ferrocenyl group is at the α-position of the steroid, below the plane of the D ring. From acidic medium it is possible to obtain and isolate the derivative with a carbenium ion in 17-α position. This ion is transformed by various nucleophiles into the C(16)-C(17)-unsaturated derivative With NaBH4 in acidic medium the reduction leads to a mixture of 17α- and 17β-ferrocenylestrol with a predominance of the β product, owing to a more favorable entrance of hydride in the α position. The oxidized derivative 17α-ferrociniumylestradiol tetrafluoroborate was prepared and its properties are described.
