Collection: Polydentate Phosphine Ligands [Catalysis]

Polydentate Phosphine Ligands [Catalysis] — contains polydentate phosphine ligands such as chiral bisphosphines and branched phosphines that bind transition metal centers through more than one phosphorus donor atom. This multidentate structure stabilizes catalyst complexes and controls the geometry and selectivity of catalytic reactions.

Polydentate Phosphine Ligands are used by organometallic chemistry and asymmetric catalysis researchers to form complexes with metals such as palladium, ruthenium, or rhodium in hydrogenation, coupling, and hydroformylation reactions. Chiral bisphosphine ligands such as the BINAP framework are commonly used to direct stereoselectivity in the synthesis of chiral compounds, while ligands based on flexible phosphine chains are used to adjust the bite angle of metal complexes in new catalyst research.

Example products in this collection: TCI X0071 135139-00-3 (S)-(-)-XylBINAP, TCI B5594 904704-23-0 N,N-Bis[(diphenylphosphino)methyl]-3-(triethoxysilyl)propylamine, TCI X0070 137219-86-4 (R)-(+)-XylBINAP, TCI B5712 131890-26-1 Bis[2-(diisopropylphosphino)ethyl]amine (ca. 10% in Tetrahydrofuran), TCI T4304 22031-12-5 1,1,1-Tris(diphenylphosphinomethyl)ethane, TCI B5957 325773-62-4 2,2'-Bis[bis(3,5-dimethylphenyl)phosphino]-1,1'-biphenyl, TCI T3153 100165-88-6 (S)-(-)-TolBINAP, TCI B5985 129648-07-3 1,2-Bis[(2R,5R)-2,5-dimethylphospholano]ethane.

Pay attention to the stereochemical configuration (R or S) of chiral ligands, optical purity, and stability against oxidation, because phosphines are easily oxidized and affect the catalytic activity of metal complexes. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
