Used as a boronic ester reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. It serves as a stable and selective source of isobutyl groups in the preparation of pharmaceuticals, agrochemicals, and functional materials. Its tetramethyl-substituted dioxaborolane structure enhances stability and reduces protodeboronation, making it suitable for reactions under mild conditions. Commonly employed in late-stage functionalization of complex molecules due to its compatibility with various functional groups.
