In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis and study of bis-terpyridine iron(II), ruthenium(II) and osmium(II) diad complexes bearing a remote ferrocenyl unit as electron donor, published in 1992-03-31, which mentions a compound: 1273-73-0, Name is Bromoferrocene, Molecular C10BrFe, Reference of Bromoferrocene.
A new terpyridine ligand (I; Fc-phterpy), containing an electroactive ferrocenyl group, was prepared by using a palladium-catalyzed aromatic cross-coupling reaction. For the corresponding iron(II), ruthenium(II) and osmium(II) homo- and heteroleptic complexes of I, phys. studies (electrochem. and spectroscopy) show a weak interaction between the ferrocenyl group and the M(terpy)2+ center in its ground state. However, evidence of a strong intramol. quenching of the excited state of these complexes was obtained in the osmium series.
This literature about this compound(1273-73-0)Reference of Bromoferrocenehas given us a lot of inspiration, and I hope that the research on this compound(Bromoferrocene) can be further advanced. Maybe we can get more compounds in a similar way.
