Product Name:(2,7-Di-tert-butyl-9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)
English Name:(2,7-Di-tert-butyl-9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)
CAS No.:221462-97-1
Aliases:4,5-Bis(diphenylphosphino)-2,7-di-tert-butyl-9,9-dimethylxanthene
Molecular Formula:C47H48OP2
Physical Properties:White to off-white crystalline powder; molecular weight 690.83; soluble in dichloromethane, chloroform, toluene and other organic solvents; stable in air; light-sensitive.
Uses:As a bulky bidentate phosphine ligand, it is widely used in transition metal-catalyzed coupling reactions involving palladium, rhodium, and ruthenium. It significantly improves catalytic activity and selectivity in Buchwald-Hartwig amination, Suzuki coupling, and C-H functionalization reactions. It is particularly suitable for constructing axially chiral compounds and serves as an important ligand in asymmetric synthesis.
