2,4-bis(4-fluorophenyl)thiophene is an organic compound characterized by its unique molecular structure, which consists of a thiophene ring (a five-membered ring with one sulfur atom) and two 4-fluorophenyl groups attached to the 2nd and 4th carbon atoms of the thiophene. The presence of fluorine atoms in the phenyl rings imparts specific electronic and steric properties to the molecule, which can influence its reactivity, stability, and potential applications. 2,4-bis(4-fluorophenyl)thiophene is of interest in the field of organic chemistry and materials science, particularly for its potential use in the synthesis of advanced materials, pharmaceuticals, and as a building block in the design of new organic compounds. Its unique structure may also contribute to its electronic properties, making it a candidate for applications in electronics and optoelectronics.

842-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 842-80-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 842-80:
(5*8)+(4*4)+(3*2)+(2*8)+(1*0)=78
78 % 10 = 8
So 842-80-8 is a valid CAS Registry Number.

Cu-catalyzed [2 + 2 + 1] cascade annulation of vinyl iodonium salts with elemental sulfur/selenium for the modular synthesis of thiophenes and selenophenes

Chen, Chao,Wang, Fei,Wu, Chao,Wu, Yaxing

supporting information, p. 945 - 949 (2022/02/01)

A [2 + 2 + 1] annulation protocol has been established for the modular synthesis of 2,4-disubstituted thiophenes/selenophenes, with excellent regioselectivity. The reactions have been catalyzed by copper salt with elemental sulfur and selenium serving as

Efficient Thiophene Synthesis Mediated by 1,3-Bis(carboxymethyl)imidazolium Chloride: C-C and C-S Bond Formation

Gisbert, Patricia,Pastor, Isidro M.

, p. 4319 - 4325 (2020/07/16)

Thiophene derivatives have been prepared by means of a functionalized imidazolium salt [1,3-bis(carboxymethyl)imidazolium chloride] acting as a catalyst. The heterogeneous catalyst has allowed to carry out the reactions with no solvent or inert atmosphere

Sulfurative self-condensation of ketones and elemental sulfur: A three-component access to thiophenes catalyzed by aniline acid-base conjugate pairs

supporting information, p. 387 - 390 (2018/02/07)

A sulfurative self-condensation method for constructing thiophenes 2 by a reaction between ketones 1 and elemental sulfur is reported. This reaction, which is catalyzed by anilines and their salts with strong acids, starts from readily available and inexp

Transition-Metal-Free Sulfuration/Annulation of Alkenes: Economical Access to Thiophenes Enabled by the Cleavage of Multiple C-H Bonds

Chen, Liang,Min, Hao,Zeng, Weilan,Zhu, Xiaoming,Liang, Yun,Deng, Guobo,Yang, Yuan

, p. 7392 - 7395 (2019/01/03)

A novel, atom economical, and transition-metal-free strategy for the synthesis of thiophenes from substituted buta-1-enes with potassium sulfide has been presented. The reaction achieves double C-S bond formations via cleavage of multiple C-H bonds and provides an efficient approach to access various functionalized thiophenes. Moreover, the strategy can also be used for the synthesis of thiophenes from 1,4-diaryl-1,3-dienes. Mechanistically, DMSO plays a role of oxidant and S3?- in situ generated from K2S is involved.
