Used as a key reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, enabling the formation of carbon-carbon bonds. Its boron-containing structure allows it to act as a boronic ester equivalent, offering enhanced stability and reactivity with aryl halides in the presence of palladium catalysts. The silyl-protected phenolic group provides orthogonal functionality, making it useful in multi-step syntheses where selective deprotection is required. Commonly employed in the preparation of complex organic molecules, including pharmaceuticals and functional materials.
