Description

3-Ethynylbenzaldehyde features a terminal alkyne group conjugated to an aldehyde moiety, enabling efficient copper-catalyzed coupling reactions. This bifunctional architecture supports modular synthesis in click chemistry and materials development, offering high reactivity under mild conditions with excellent functional group tolerance.

Application

3-Ethynylbenzaldehyde serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to conjugated enynes and extended π-systems. Its aldehyde functionality supports sequential transformations including Wittig reactions, nucleophilic additions, and reductive amination, while the terminal alkyne exhibits high compatibility with Sonogashira and click chemistry protocols. Bench-stable and readily purified by column chromatography, it functions effectively in multi-step syntheses of functionalized aromatic scaffolds and heterocyclic systems relevant to medicinal chemistry and materials science.
