In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The anomalous electrochemistry of the ferrocenylamines, published in 1986, which mentions a compound: 1273-73-0, mainly applied to ferrocenylamine electrochem oxidation; substituent effect electrochem ferrocenylamine; resonance ferrocenylamine, Recommanded Product: Bromoferrocene.

In the electrochem. of ferrocenylamines, the amine substituent acts as an unusually potent activating group for ferrocene oxidation, as shown by various Hammett-type correlations, with ferrocenylamine oxidizing at a potential 0.37 V more neg. than ferrocene itself. Triferrocenylamine, a compound with a nearly planar N, produces three reversible oxidation waves, the first of which is 0.31 neg. of ferrocene’s oxidation These and other data suggest that resonance interaction between ferrocene and the N lone pair is an important factor in ferrocene oxidation This contrasts with conclusions of earlier studies in which ferrocenes, with primarily electron-withdrawing groups, were examined

Application In Synthesis of Bromoferrocene. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Mechanically-tunable quantum interference in ferrocene-based single-molecule junctions. Author is Camarasa-Gomez, Maria; Hernangomez-Perez, Daniel; Inkpen, Michael S.; Lovat, Giacomo; Fung, E-Dean; Roy, Xavier; Venkataraman, Latha; Evers, Ferdinand.

Ferrocenes are ubiquitous organometallic building blocks that comprise a Fe atom sandwiched between two cyclopentadienyl (Cp) rings that rotate freely at room temperature Of widespread interest in fundamental studies and real-world applications, they have also attracted some interest as functional elements of mol.-scale devices. Here, the impact of the configurational degrees of freedom of a ferrocene derivative on its single-mol. junction conductance is investigated. Measurements indicate that the conductance of the ferrocene derivative, which is suppressed by two orders of magnitude as compared to a fully conjugated analog, can be modulated by altering the junction configuration. Ab initio transport calculations show that the low conductance is a consequence of destructive quantum interference effects that arise from the hybridization of metal-based d-orbitals and the ligand-based π-system. By rotating the Cp rings, the hybridization, and thus the quantum interference, can be mech. controlled, resulting in a conductance modulation that is seen exptl.

Now Is The Time For You To Know The Truth About 1273-73-0

Here is a brief introduction to this compound(1273-73-0)Computed Properties of C10BrFe, if you want to know about other compounds related to this compound(1273-73-0), you can read my other articles.

Computed Properties of C10BrFe. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Dye regeneration and charge recombination in dye-sensitized solar cells with ferrocene derivatives as redox mediators. Author is Daeneke, Torben; Mozer, Attila J.; Kwon, Tae-Hyuk; Duffy, Noel W.; Holmes, Andrew B.; Bach, Udo; Spiccia, Leone.

Ferrocene compounds are promising redox shuttles for application in dye-sensitized solar cells (DSCs). Chem. modification of the cyclopentadienyl rings is easily achievable affording almost unlimited variation of the redox properties. This allows fine-tuning of the driving force for dye-regeneration and optimization of the energy conversion efficiency of DSCs. Herein, six ferrocene derivatives have been chosen for investigation which cover the large redox potential range of 0.85 V, by virtue of simple alkylation and halogenation of the cyclopentadienyl ring, and enable improved matching of the energy levels of the sensitizer and the electrolyte. Although the focus of this work was to examine the effect of the redox potential on charge transfer processes, DSCs were fabricated which achieved high energy conversion efficiencies of over 5%. Charge transfer reactions were studied to reveal the dependence of the dye regeneration rate, recombination losses and recombination pathways on the reaction driving force. An increase in redox potential led to a higher efficiency due to higher open circuit potentials until a threshold is reached. At this threshold, the driving force for dye regeneration (18 kJ mol-1, ΔE = 0.19 V) becomes too small for efficient device operation, leading to rapid recombination between the oxidized dye and electrons in the TiO2 conduction band. As a result of this work guidelines can be formulated to aid the selection of redox couples for a particular sensitizer in order to maximize the utilization of incident solar energy.

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.Wong, Wai-Yeung; Wong, Wing-Tak; Cheung, Kung-Kai researched the compound: Bromoferrocene( cas:1273-73-0 ).Application of 1273-73-0.They published the article 《Metallosupramolecular cluster assemblies based on donor-acceptor type structural frameworks. Syntheses, crystal structures and spectroscopic properties of novel triosmium alkylidyne carbonyl clusters bearing remote ferrocenyl units as electron donors》 about this compound( cas:1273-73-0 ) in Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry. Keywords: metallosupramol cluster donor acceptor framework; osmium alkylidyne ferrocenyl tetranuclear cluster; crystal structure osmium alkylidyne ferrocenyl cluster; mol structure osmium alkylidyne ferrocenyl cluster. We’ll tell you more about this compound (cas:1273-73-0).

Two pyridyl ligands containing redox-active ferrocenyl groups [Fe(η5-C5H5)(η5-C5H4C6H4R)] [R = C5H4N (I), NCH(C5H4N) (II)] have been prepared using a palladium-catalyzed aromatic cross-coupling reaction. Treatment of the cluster [Os3(μ-H)3(CO)9(μ3-CCl)] with one equivalent of 1,8-diaza-bicyclo[5.4.0]undec-7-ene in the presence of a ten-fold excess of the ferrocenyl ligands I and II produces the compounds [Os3(μ-H)2(CO)9(μ3-CNC5H4R’)] [R’ = C6H4(η5-C5H4)Fe(η5-C5H5) 1, R’ = CHNC6H4(η5-C5H4)Fe(η5-C5H5) 2] resp. in good yields. Both compounds 1 and 2 exhibit donor-π-acceptor structural frameworks and show considerable neg. solvatochromism in their UV/VIS spectra. Unlike 1 and 2 which possess extended donor-π-acceptor nature, the ferrocenyl-phosphine cluster derivative [Os3(μ-H)2(CO)9{μ3-CPPh2(η5-C5H4)Fe(η5-C5H4PPh2)}] 3 has also been synthesized in moderate yield by the same synthetic route using 1,1′-bis(diphenylphosphino)ferrocene as the nucleophile. The new clusters 1-3 have all been fully characterized by both spectroscopic and crystallog. methods. Conceptually, the classification of 1-3 as supermols. is straightforward, since mol. subunits with well defined intrinsic properties can be easily identified, thus affording a new type of covalently linked donor-acceptor system. Both structural features and spectroscopic data for compounds 1-3 are fully consistent with a zwitterionic formulation for these supramol. species. These results suggest that a strong interaction exists between the ferrocenyl moiety and the OS3C core in their ground states.
