Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its boronate ester group readily participates in palladium-catalyzed couplings with aryl or vinyl halides, making it valuable for constructing complex organic molecules, especially in pharmaceutical and agrochemical research. The cyclopropylethynyl group acts as a versatile building block, allowing further functionalization or serving as a rigid structural motif to influence molecular shape and bioactivity. Commonly employed in late-stage diversification due to its stability and reactivity under mild conditions.
