2-Ethynylpyridine

These compounds have the same murcko framework: 2-ethynylpyridine

Addition Reactions: The triple bond in 2-ethynylpyridine can undergo addition reactions with electrophiles or nucleophiles. For example, it can undergo addition with hydrogen halides (HCl, HBr, etc.) to form vinyl halides.
Alkylation and Acylation: The aromatic ring can undergo alkylation or acylation reactions with appropriate alkyl halides or acyl chlorides in the presence of a Lewis acid catalyst to yield alkyl or acyl-substituted pyridines.
Sonogashira Coupling: Since 2-ethynylpyridine has an alkyne moiety, it can undergo Sonogashira coupling with aryl halides in the presence of a palladium catalyst and a base to form substituted alkynes.
Hydrogenation: The triple bond can be hydrogenated under catalytic hydrogenation conditions to yield the corresponding alkene.
Nucleophilic Addition to the Triple Bond: The triple bond can also undergo nucleophilic addition reactions with strong nucleophiles like organolithium or Grignard reagents to yield substituted alkynes.
Electrophilic Aromatic Substitution: The aromatic ring in 2-ethynylpyridine can undergo electrophilic aromatic substitution reactions, such as nitration, sulfonation, halogenation, etc., depending on the reaction conditions and reagents used.
Cross-Coupling Reactions: It can undergo various cross-coupling reactions, such as Suzuki coupling, Heck coupling, etc., to form biaryl compounds or other functionalized products.
