Used as a reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, where it acts as a boron-based partner to form carbon-carbon bonds. Its cyclic structure and tetraalkyl substitution enhance stability and reactivity, making it valuable for introducing cyclopentyl groups in pharmaceutical and agrochemical intermediates. It is also employed in the synthesis of functional materials, including conjugated polymers and liquid crystals, due to its reliable performance in palladium-catalyzed transformations.
