Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about 1-(1′-Bromoferrocenyl)silver.Formula: C10BrFe.
Treating 0.5 g 1-bromo-1′-ferroceneboronic acid with Ag2O from 0.5 g Ag NO3 in NH4OH and heating briefly gave 53% 1-(1′-bromoferrocenyl)-silver, decomposed 125-6°. This with concentrated HCl 10 min gave 70% bromoferrocene, while pyrolysis in xylene gave a Ag mirror and 60% bis(1′-bromoferrocenyl), m. 138-40°. Treated with HgBr2 in C6H6 the Ag salt gave 80% 1-(1′-bromoferrocenyl)-mercuric bromide, m. 143-5°. The Ag derivative and BiBr3 in C6H6 in 3-4 hrs gave bromoferrocene and 50% tris(1′-bromoferrocenyl)bismuth, m. 179.5-81°. This kept in concentrated HCl 0.5 hr, then treated with aqueous NH4OH to neutrality, then percolated with H2S, gave a precipitate which was used for estimation of Bi after washing and drying to constant weight
As far as I know, this compound(1273-73-0)Formula: C10BrFe can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
