Widely used as a catalyst in cross-coupling reactions, especially in Suzuki, Heck, and Negishi reactions, enabling the formation of carbon-carbon bonds in organic synthesis. It is particularly effective for aryl-aryl coupling, making it valuable in pharmaceutical, agrochemical, and materials science industries. Its stability and high activity allow reactions to proceed under mild conditions with good yields. Commonly employed in the synthesis of complex molecules such as drugs, natural products, and conjugated polymers for electronic devices.
