(2-Ethynylphenyl)boronic acid features a pendant alkyne group conjugated to a boronic acid moiety, enabling direct incorporation into Sonogashira coupling reactions. This bifunctional architecture facilitates efficient C–C bond formation under mild conditions, delivering substituted arylalkynes with high functional group tolerance. The compound exhibits bench-stable handling and compatibility with diverse reaction matrices in synthetic and medicinal chemistry workflows.
(2-Ethynylphenyl)boronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of biaryl and styryl scaffolds. Its ethynyl group offers orthogonal reactivity for downstream functionalization via copper-catalyzed coupling or cyclization, while the boronic acid moiety ensures good bench stability and compatibility with diverse reaction conditions. Ideal for medicinal chemistry and materials synthesis workflows requiring precise structural control.
