Home Chemistry Organic Building Blocks Alkynyls 1,4-Bis(Phenylethynyl)Benzene
Halogenation: 1,4-bis(phenylethynyl)benzene can undergo halogenation reactions, where halogens like chlorine or bromine are added to the triple bonds. This can be achieved using halogenating agents like N-bromosuccinimide (NBS) or chlorine gas.
Hydrogenation: Reduction of the triple bonds in 1,4-bis(phenylethynyl)benzene can be achieved using hydrogen gas in the presence of a suitable catalyst like palladium on carbon or Lindlar's catalyst, leading to the formation of 1,4-bis(phenyl)benzene.
Suzuki Coupling: 1,4-bis(phenylethynyl)benzene can undergo Suzuki coupling reactions, enabling the introduction of various aryl or vinyl groups to its structure using suitable boronic acid or boronate ester reagents.
Oxidation: The compound can be oxidized using strong oxidizing agents to convert the phenylacetylene groups into carboxylic acid groups. Oxidants like potassium permanganate (KMnO4) or peroxides can be employed for this purpose.
Diels-Alder Reaction: 1,4-bis(phenylethynyl)benzene can participate in Diels-Alder reactions, where it can react with dienes to form cyclic products. This can be useful for generating complex aromatic compounds.
Arylation: The benzene ring of 1,4-bis(phenylethynyl)benzene can be arylated using electrophilic aromatic substitution reactions, allowing for the introduction of various substituents onto the aromatic ring.
