Nesmeyanov, A. N.; Sazonova, N. S.; Sazonova, V. A.; Meskhi, L. M. published the article 《1-(1′-Bromoferrocenyl)silver》. Keywords: bismuth estimation; bismuth ferrocene compound; silver ferrocene compound; silver ferrocene compound; ferrocenes; iron organic compound.They researched the compound: Bromoferrocene( cas:1273-73-0 ).Category: thiazolidine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1273-73-0) here.
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
