5-BROMO-2-ETHYNYL-THIOPHENE

Description:

5-Bromo-2-ethynylthiophene 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 5-position and an ethynyl group at the 2-position contributes to its unique reactivity and properties. This compound is typically a yellow to brown solid and is known for its applications in organic synthesis, particularly in the development of electronic materials and pharmaceuticals. Its structure allows for various substitution reactions, making it a versatile intermediate in the synthesis of more complex molecules. The ethynyl group enhances its reactivity, enabling coupling reactions that are valuable in materials science. Additionally, the bromine substituent can serve as a leaving group in nucleophilic substitution reactions. As with many organobromine compounds, it is important to handle 5-bromo-2-ethynylthiophene with care due to potential toxicity and environmental concerns associated with brominated compounds. Proper safety protocols should be followed when working with this substance in a laboratory setting.

2-Bromo-5-ethynylthiophene

CAS: 105995-73-1

2-Bromo-5-ethynylthiophene is a terminal alkyne that can be used as a ligand, an additive, or as an intermediate in organic synthesis. 2-Bromo-5-ethynylthiophene can be obtained by heating ethynylacetylene with bromine and sulfuric acid. It is insoluble in water and other solvents, and has two different conformations. The two isomers are distinguished by their reaction time to form the diacetate monomer. The diacetate monomer reacts more quickly than the monoacetate monomer because it has a higher energy barrier. 2-Bromo-5-ethynylthiophene can also be used in devices such as OLEDs and solar cells.
