Properties and Exciting Facts About 1273-73-0

If you want to learn more about this compound(Bromoferrocene)Recommanded Product: Bromoferrocene, you may wish to communicate with the author of the article,or consult the relevant literature related to this compound(1273-73-0).

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

Ferrocene and cobaltocene and their derivatives are studied as new redox materials for redox flow cells. Their high reaction rates and moderate solubility are attractive properties for their use as active materials. The cyclability experiments are carried out in a static cell; the results showed that these materials exhibit stable capacity retention and predictable discharge potentials, which agree with the potential values from the cyclic voltammograms. The diffusion coefficients of these materials are 2 to 7 times higher than those of other non-aqueous materials such as vanadium acetylacetonate, iron tris(2,2′-bipyridine) complexes, and an organic benzene derivative

Discovery of 1273-73-0

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

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 Measurements of structural and quadrupole coupling parameters for bromoferrocene using microwave spectroscopy, published in 1997-11-01, which mentions a compound: 1273-73-0, mainly applied to ferrocene bromo microwave spectroscopy; quadrupole coupling bromoferrocene; rotational spectra bromoferrocene; mol structure bromoferrocene, SDS of cas: 1273-73-0.

Rotational spectra for two isotopomers of bromoferrocene were measured using pulsed-beam Fourier transform microwave spectroscopy. Transitions were observed for the 79Br and 81Br isotopomers in the 5-9 GHz range. Rotational constants and the quadrupole coupling tensors were obtained. The rotational constants and quadrupole coupling parameters for 79Br are A = 1272.110(1), B = 516.1125(2), C = 441.3775(2), eQqaa=267.16(3), eQqab=-409.81(4), and eQqbb=21.49(4), and those for 81Br are A = 1271.045(4), B = 510.0079(2), C = 436.7687(2), eQqaa=225.40(6), eQqab=-341.62(4), and eQqbb=15.65(4). The measured rotational constants were used to determine the following structural parameters of bromoferrocene: r(Fe-(C5H5))=1.63(2), r(Fe-(C5H4Br))=1.67(3), r(C-Br)=1.875(11), and r(C-C)=1.433(1) A. The values of the quadrupole coupling parameters in the principal quadrupole axis systems and the C-Br bond axis systems are compared with similarly derived parameters for chloroferrocene, chlorobenzene, and bromobenzene. Previous data for chloroferrocene was reanalyzed to obtain refined quadrupole parameters.
