Synthesis Using Phosphine and Bisphosphine Stabilizers

Phosphine-based ligands are weU known to coordinate to palladium and form inorganic compounds. However, their use as stabUizers for Pd nanoparhcles has not been extensively uhUzed. In 2003, Hyeon s group inveshgated the use of phosphine ligands as stabilizers for Pd nanoparhcles [49] by preparing a 

Chiral bisphosphine ligands have found extensive applications in asymmetric catalysis, which is an important reaction in the synthesis of natural products. In 2003, Fujihara reported the first example of bisphosphine-stabihzed Pd nanoparticles [50], 2,2 -Bis(diphenylphosphino)-l,T-binaphthyl (BINAP), a chiral biaryl
