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.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1273-73-0, is researched, SMILESS is Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25, Molecular C10BrFeJournal, Article, Organometallics called Halide-Mediated Ortho-Deprotonation Reactions Applied to the Synthesis of 1,2- and 1,3-Disubstituted Ferrocene Derivatives, Author is Zirakzadeh, Afrooz; Herlein, Alexander; Gross, Manuela A.; Mereiter, Kurt; Wang, Yaping; Weissensteiner, Walter, the main research direction is halide deprotonation disubstituted ferrocene derivative; crystal mol structure bromodiiodoferrocene.Computed Properties of C10BrFe.

The ortho-deprotonation of halide-substituted ferrocenes by treatment with lithium tetramethylpiperidide (LiTMP) has been investigated. Iodo-, bromo-, and chloro-substituted ferrocenes were easily deprotonated adjacent to the halide substituents. The synthetic applicability of this reaction was, however, limited by the fact that, depending on the temperature and the degree of halide substitution, scrambling of both iodo and bromo substituents at the ferrocene core took place. Iodoferrocenes could not be transformed selectively into ortho-substituted iodoferrocenes since, in the presence of LiTMP, the iodo substituents scrambled efficiently even at -78°, and this process had occurred before electrophiles had been added. Bromoferrocene and certain monobromo-substituted derivatives, however, could be efficiently ortho-deprotonated at low temperature and reacted with a number of electrophiles to afford 1,2- and 1,2,3-substituted ferrocene derivatives For example, 2-bromo-1-iodoferrocene was synthesized by ortho-deprotonation of bromoferrocene and reaction with the electrophiles diiodoethane and diiodotetrafluoroethane, resp. In this and related cases the iodide scrambling process and further product deprotonation due to the excess LiTMP could be suppressed efficiently by running the reaction at low temperature and in inverse mode. In contrast to the low-temperature process, at room temperature bromo substituents in bromoferrocenes scrambled in the presence of LiTMP. Chloro- and 1,2-dichloroferrocene could be ortho-deprotonated selectively, but in neither case was scrambling of a chloro substituent observed As a further application of this ortho-deprotonation reaction, a route for the synthesis of 1,3-disubstituted ferrocenes was developed. 1,3-Diiodoferrocene was accessible from bromoferrocene in four steps. On a multigram scale an overall yield of 41% was achieved. 1,3-Diiodoferrocene was further transformed into sym. 1,3-disubstituted ferrocenes (1,3-R2Fc; R = CHO, COOEt, CN, CH:CH2).

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Synthesis, chemical reactivity and electrochemical behaviour of mono- and difluoro metallocenes.Related Products of 1273-73-0.

Syntheses of mono- and 1,1′-difluoro-substituted metallocenes (ferrocene, ruthenocene) and of asym. 1,1′-disubstituted ferrocenes with one substituent being fluorine are described. Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the exptl. conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1′-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, resp. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I). Finally, 1-bromo-1′-fluoro-ferrocene turns out to be an ideal starting material for further fluoro-substituted ferrocene derivatives

The X-ray structure of 17α-ferrocenylestradiol shows that the ferrocenyl group is at the α-position of the steroid, below the plane of the D ring. From acidic medium it is possible to obtain and isolate the derivative with a carbenium ion in 17-α position. This ion is transformed by various nucleophiles into the C(16)-C(17)-unsaturated derivative With NaBH4 in acidic medium the reduction leads to a mixture of 17α- and 17β-ferrocenylestrol with a predominance of the β product, owing to a more favorable entrance of hydride in the α position. The oxidized derivative 17α-ferrociniumylestradiol tetrafluoroborate was prepared and its properties are described.
