4-Bromo-2-cyanothiophene

Description:

4-Bromo-2-cyanothiophene is an organic compound characterized by its thiophene ring, which is a five-membered aromatic heterocycle containing sulfur. The presence of a bromine atom at the 4-position and a cyano group at the 2-position contributes to its unique chemical properties. This compound typically exhibits a pale yellow to light brown appearance and is known for its moderate solubility in organic solvents. It is often utilized in organic synthesis and materials science, particularly in the development of electronic materials and as a building block in the synthesis of various functionalized compounds. The bromine substituent can enhance reactivity, making it useful in cross-coupling reactions, while the cyano group can serve as a strong electron-withdrawing group, influencing the electronic properties of the molecule. Additionally, 4-Bromo-2-cyanothiophene may exhibit interesting photophysical properties, making it a candidate for applications in organic photovoltaics and other optoelectronic devices. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.

4-Bromothiophene-2-carbonitrile

CAS: 18791-99-6

4-Bromothiophene-2-carbonitrile (4BTCC) is a chemical compound that yields monomers with a distal spacer. The 4BTCC monomer can be synthesized by reacting bromoacetaldehyde and 2-cyanopyridine, which have been shown to have the same electron density, in the presence of copper(II) chloride. The activation energy for this reaction was found to be 10.5 kJ/mol. The fluorine atom in 4BTCC has been shown to be crucial for its structural activity and bioactivity. The structure of 4BTCC is composed of a C–H bond and a C=N bond that are each bonded to two fluorine atoms.
