Used primarily as an intermediate in Suzuki-Miyaura cross-coupling reactions, this compound enables the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group readily reacts with aryl or vinyl halides in the presence of a palladium catalyst, making it valuable in pharmaceutical and agrochemical research for constructing biaryl systems. It is especially useful when introducing the 3,4-dihydro-2H-benzo[b][1,4]dioxepin moiety, a scaffold found in bioactive molecules and drug candidates. The reagent enhances synthetic efficiency due to its stability and reactivity under mild conditions.
