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.Sorriso, Salvatore researched the compound: Bromoferrocene( cas:1273-73-0 ).Synthetic Route of C10BrFe.They published the article 《Energy barrier to internal rotation in some ferrocene derivatives from dielectric measurements》 about this compound( cas:1273-73-0 ) in Journal of Organometallic Chemistry. Keywords: dipole moment ferrocene halo; halo ferrocene rotation barrier; conformation dihaloferrocene. We’ll tell you more about this compound (cas:1273-73-0).
Dipole moments have been measured in n-decane at 5-130° for the compounds monochloro-, 1,1′-dichloro-, monobromo-, 1,1′-dibromo-, monoiodo-, and 1,1′-diiodoferrocene. The energy barriers to rotation of the two cyclopentadiene rings about the bond to iron have been calculated Free rotation exists in the parent mol., ferrocene. Steric effects between the halo substituents of one ring and the H atoms of the other ring are small.
I hope my short article helps more people learn about this compound(Bromoferrocene)Synthetic Route of C10BrFe. Apart from the compound(1273-73-0), you can read my other articles to know other related compounds.
