Used as a key reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. Its steric bulk and electron-rich nature enhance selectivity and reactivity with aryl halides, making it valuable in the preparation of complex organic molecules, including pharmaceuticals and agrochemicals. Also employed in the synthesis of functional materials such as organic semiconductors and liquid crystals due to its stability and efficient coupling performance.
