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.Riemschneider, Randolph; Wucherpfennig, Wolfgang researched the compound: Bromoferrocene( cas:1273-73-0 ).Computed Properties of C10BrFe.They published the article 《Ferrocene and related compounds. VIII. Internal rotation of the ferrocene molecule》 about this compound( cas:1273-73-0 ) in Zeitschrift fuer Naturforschung, Teil B: Anorganische Chemie, Organische Chemie, Biochemie, Biophysik, Biologie. Keywords: DIPOLE MOMENT FERROCENES; FERROCENES DIPOLE MOMENT; INTERNAL ROTATION FERROCENES; ROTATION INTERNAL FERROCENES. We’ll tell you more about this compound (cas:1273-73-0).
cf. CA 59, 5195h. The dipole moments of chloro- and bromoferrocene, measured at 20°, and of 1,1-dichloro- and 1,1-dibromoferrocene, measured at +5 and -20 to +130°, resp., are nearly identical to those of the corresponding monohalobenzenes. The values obtained for the dipole moments of the dihaloferrocenes at various temperatures can be used to calculate the energy differences of the 3 min. of the potential energy curves of internal rotation corresponding to the 3 antiprismatic conformations. A comparison of the curves with those of 1,2-dihaloethanes reveals that the energy barriers of internal rotation are smaller in ferrocene than in ethane. Attempts were made to calculate the contours of the potential energy curves of ferrocene and its halogen derivatives
Although many compounds look similar to this compound(1273-73-0)Computed Properties of C10BrFe, numerous studies have shown that this compound(SMILES:Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25), has unique advantages.
