A protonated diphosphine tetrafluoroborate salt used as a precursor for generating the free diphosphine ligand or transition-metal phosphine complexes. Commonly employed in homogeneous catalysis, catalyst precursor preparation, palladium-, rhodium-, ruthenium-, iridium- and nickel-catalyzed coupling and hydrogenation reactions, organometallic synthesis, and pharmaceutical process research.
