Collection: Phosphite Ligands [Catalysis]

Phosphite Ligands [Catalysis] — covers trivalent phosphite esters, both triaryl and trialkyl phosphites as well as their cyclic derivatives, which have a lone pair of electrons on the phosphorus atom to coordinate with metals. The electron-donating and steric properties of their aryl groups make this group an important ligand in coordination chemistry and transition metal catalysis.

Phosphite Ligands are used as supporting ligands on nickel-, palladium-, or rhodium-based catalysts in hydroformylation, asymmetric hydrogenation, and Arbuzov reactions for forming phosphorus-carbon bonds. Organometallic synthesis researchers choose derivatives with large aryl groups such as tert-butylphenyl to tune the steric and electronic properties of the resulting catalyst complexes.

Example products in this collection: TCI T3353 66470-81-3 Tris(1,1,1,3,3,3-hexafluoro-2-propyl) Phosphite, TCI P1175 620-42-8 Tri-p-tolyl Phosphite, TCI T2645 16352-18-4 4,4,5,5-Tetramethyl-1,3,2-dioxaphospholane 2-Oxide, TCI P1260 6095-42-7 Trihexyl Phosphite, TCI T0510 101-02-0 Triphenyl Phosphite, TCI P1416 2622-08-4 Tri-o-tolyl Phosphite, TCI T0362 102-85-2 Tributyl Phosphite, TCI P1421 31570-04-4 Tris(2,4-di-tert-butylphenyl) Phosphite.

Pay attention to the substituent groups on the phosphorus atom (aryl or alkyl, including the steric size of tert-butyl groups), purity, and the material's sensitivity to air moisture during storage. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
