This chemical is primarily used as a ligand in catalytic processes, particularly in transition metal-catalyzed reactions. It is effective in facilitating cross-coupling reactions, such as Suzuki-Miyaura and Heck reactions, due to its sterically hindered and electron-rich phosphine structure. The compound enhances the stability and activity of metal catalysts, improving reaction efficiency and selectivity. It is also employed in various synthetic applications, including the synthesis of pharmaceuticals and fine chemicals. Additionally, its application extends to materials science, where it is used in the development of advanced polymers and coordination complexes.
