Category: thiazolidine. 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 Triferrocenylborane and its amine adducts.
The synthesis and characterization by IR, diffuse reflectance, thermogravimetric and Moessbauer techniques of triferrocenylborane and its adducts with ammonia, methylamine, ethylamine, propylamine, dimethylamine, and pyridine, are reported. Bands in the 1250 and 760 cm-1 IR regions are assigned to vibration of the B-C and B-N bonds, resp. In the visible region the spectra show besides the two typical ferrocene bands, shifted to lower frequency, a third one around 15,000 cm-1, probably due to the splitting of the first excited level of ferrocene caused by its decrease in symmetry when bonding covalently to boron in triferrocenylborane. Moessbauer spectroscopy shows that the s-electron d. around the 57Fe nucleus is higher in triferrocenylborane than in ferrocene; part of this s-electron d. is decreased by addnl. d-electron d. in the case of the adduct compounds
