Electric Literature of C10BrFe. 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 Dipole moments and internal rotation in 1,1′-dihaloferrocenes.
The dipole moments of bromoferrocene, iodoferrocene, 1,1′-dibromoferrocene, and 1-1′-diiodoferrocene have been measured in C6H6. They indicate that the potential barrier between the cis and trans forms, which is very small for 1,1′-dichloroferrocene, increases for 1,1′-dibromo- and 1,1′-diiodoferrocene. The potential energy function shows min. at 36°, 108° and 180°. The differences ΔE1 = E36° – E180° for the series have been calculated on the assumption that the min. at 180° and 108° are equal. The values obtained are consistent with increasing steric hindrance in the series Cl, Br, I.
