CAS:9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene is a chelate ligand that is used in the coordination of palladium. It has been shown to be a good ligand for the synthesis of highly active catalysts for various chemical reactions. 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene binds to metal complexes in an octahedral geometry to form a planar structure with an average distance between nitrogen atoms of 2.1 Å and a coordination number of six. The x-ray crystal structures show that the phosphine groups are coplanar and the phenyl groups are coplanar within each ring plane. The calculated activation energies for different reaction pathways range from 12 kJ/mol to 14 kJ/mol.Formel:C39H32OP2Reinheit:Min. 98 Area-%Farbe und Form:PowderMolekulargewicht:578.62 g/molXantPhos (4,5-Bis(Diphenylphosphino)-9,9-Dimethylxanthine) extrapure, 98%
