This compound is a potassium organotrifluoroborate salt primarily used in organic synthesis as a nucleophilic coupling partner in Suzuki-Miyaura cross-coupling reactions. It enables the introduction of the 2-((tetrahydro-2H-pyran-2-yl)oxy)ethyl group into molecules, facilitating the formation of carbon-carbon bonds with aryl or vinyl halides. The tetrahydro-2H-pyran (THP) protecting group safeguards the hydroxyl functionality, enhancing the compound's stability, solubility, and handling properties under various reaction conditions. It is employed in the preparation of complex organic molecules, including pharmaceuticals and agrochemicals, where precise transfer of the protected alkyl chain is required. Its applications also extend to the development of new materials and catalysts, leveraging its robust reactivity.
