[二叔丁基(氯化)膦]二氯化钯(II)二聚体 (CAS No.386706-33-8)

Product Name:Di-tert-butyl(chloro)phosphine palladium(II) chloride dimer

English Name:Di-tert-butyl(chloro)phosphine palladium(II) chloride dimer

CAS No.:386706-33-8

Aliases:Dichlorobis(di-tert-butylchlorophosphine)dipalladium(II) dimer, [PdCl2(P(tBu)2Cl)]2

Molecular Formula:C16H36Cl6P2Pd2

Physical Properties:Pale yellow to amber to dark green powder crystals. Soluble in dichloromethane, chloroform, toluene and other organic solvents; slightly soluble in ethanol; insoluble in water. Relatively stable to air and moisture, but recommended to store sealed under inert atmosphere in the dark, avoiding thermal decomposition.

Uses:Used as a palladium catalyst precursor in cross-coupling reactions such as Suzuki coupling and Buchwald-Hartwig amination, generating highly active Pd(0) catalytic species in situ. The bulky di-tert-butylchlorophosphine ligand enhances catalytic stability and activity, making it suitable for the synthesis of fine chemicals and pharmaceutical intermediates.
