Synthetic Route of C10BrFe. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Synthesis, X-ray structure and chemical properties of 17α-ferrocenylestradiol. Author is Vichard, Dominique; Gruselle, Michel; Jaouen, Gerard; Nefedova, Marina N.; Mamedyarova, Irina A.; Sokolov, Viatcheslav I.; Vaissermann, Jacqueline.

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.
