Used as a key reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a boronic ester equivalent, enabling the formation of carbon-carbon bonds between aromatic or vinyl halides and boron-containing partners. The tetrahydropyranylidene group enhances stability and influences reactivity, making it useful in the synthesis of complex organic molecules, including pharmaceuticals and functional materials. Its structure allows for selective transformations under mild conditions, which is advantageous in multi-step synthetic routes.
