Widely used as a ligand in transition metal catalysis, this compound plays a key role in forming complexes with metals such as palladium, ruthenium, and iridium. These complexes are effective in cross-coupling reactions, including Suzuki and Heck reactions, which are essential for forming carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its bipyridine backbone and phosphine group provide strong chelating ability, enhancing catalyst stability and activity. It is also employed in photoredox catalysis and in the development of luminescent materials due to its ability to tune the electronic properties of metal centers.
