Benzenamine, 4-[(1E)-2-(4-bromophenyl)ethenyl]-, also known as 4-[(1E)-2-(4-bromophenyl)ethenyl]aniline or 4-[(E)-2-(4-bromophenyl)vinyl]aniline, is an organic compound with the chemical formula C14H12BrN. It is a derivative of aniline, featuring a vinyl group (C2H3) attached to the 4-position of the aniline ring, with one of the vinyl's phenyl groups substituted with a bromine atom at the para position. Benzenamine, 4-[(1E)-2-(4-bromophenyl)ethenyl]- is characterized by its yellow crystalline appearance and is soluble in organic solvents. It is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and dyes due to its unique chemical structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 7297-51-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7297-51:
(6*7)+(5*2)+(4*9)+(3*7)+(2*5)+(1*1)=120
120 % 10 = 0
So 7297-51-0 is a valid CAS Registry Number.

Zn(II)-Induced Ground-State π-Deconjugation and Excited-State Electron Transfer in N,N-Bis(2-pyridyl)amino-Substituted Arenes

Yang, Jye-Shane,Lin, Yan-Duo,Lin, Yu-Hsi,Liao, Fen-Ling

, p. 3517 - 3525 (2007/10/03)

The synthesis and X-ray crystal structures of two N,N-bis(2-pyridyl)amino (dpa)-substituted aromatic systems (Ar-dpa) 1 (Ar = 4,4′-disubstituted trans-stilbene) and 2 (Ar = 1,4-disubstituted benzene) and their ZnCl 2 complexes (1/ZnCl2 and 2/ZnCl2) are reported. The fluoroionophoric behavior of 1-2 in response to Zn(II) in acetonitrile also has been investigated. In addition, compound 3DPA has been prepared and served as a π-deconjugated model for 1DPA. The observed crystal structures for 1/ZnCl2 and 2/ZnCl2 could be divided into two distinct types, the planar and the twisted forms, depending on the aryl-dpa (Cph-NC3) dihedral angle. The twisted form is more favorable for these complexes unless the arene has a strong " push-pull" character. Nonetheless, the degree of π-conjugation between the N-pyridyl and the N-aryl group is reduced in both complex forms when compared with the free ligands. Such a Zn(II)-induced π-deconjugation not only directly affects the internal charge transfer (ICT) fluorescence of the dpa-substituted stilbenes but also facilitates the occurrence of photoinduced electron transfer (PET) from the stilbene donor to the dpa/Zn(II) acceptor. The PET process is particularly important in accounting for the observed Zn-(II)-induced fluorescence quenching for 1DPA as well as 3DPA.

Spectroscopic characterization by laser flash photolysis of electrophilic intermediates derived from 4-aminostilbenes. Stilbene "nitrenium" ions and quinone methide imines

Bose, Rohit,Ahmad, Abid R.,Dicks, Andrew P.,Novak, Michael,Kayser, Kelly J.,McClelland, Robert A.

, p. 1591 - 1599 (2007/10/03)

This paper reports the observation in water-acetonitrile solutions of two electrophiles derived from 4-amino- and 4-acetylaminostilbene carcinogens - the 'nitrenium' ion ArCH=CHC6H4-N+R and the quinone methide imine ArCHOH
