Safety 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 Action of halogens on ferrocenylgold-triphenylphosphine.
Ph3P.AuC5H4FeC5H5 (I) brominated in CCl4 at -20° to a blue, then yellow material and after evaporation gave 55% bromoferrocene and 18% biferrocenyl along with 70% Ph3P.AuBr. Similar results were obtained at -50° in CH2Cl2. I chlorinated as above to 26% chloroferrocene, 70% biferrocenyl, and 98% Ph3P.AuCl. Iodination gave 82% iodoferrocene and 89% Ph3P.AuI.
