DICHLOROBIS(TRI-O-TOLYLPHOSPHINE)PALLADIUM(II) Usage And Synthesis
Chemical PropertiesYellow to orange crystalline powder
Usessuzuki reaction
UsesDichlorobis(tri-o-tolylphosphine)palladium(II) is used in reaction of tributyltin enolates, prepared in situ from tributyltin methoxide and enol acetates, with aryl bromides, coupling reaction of aryl bromides with vinylic acetates.
General DescriptionDichlorobis(tri-o-tolylphosphine)palladium(II) is a useful catalyst for C-C and C-N coupling reactions.
reaction suitabilityreaction type: Buchwald-Hartwig Cross Coupling Reaction
reaction type: Cross Couplings
reaction type: Heck Reaction
reaction type: Hiyama Coupling
reaction type: Negishi Coupling
reaction type: Sonogashira Coupling
reaction type: Stille Coupling
reaction type: Suzuki-Miyaura Coupling
reagent type: catalyst
core: palladium
SynthesisUnder the protection of argon, 15.5 g of tetrakis(triphenylphosphine)palladium(0) (Pd (PPh3) 4) (4 mmol), 7 mmol of p-bromotoluene, 0.5246 g of triphenylmercury (PPh3) (2 mmol) and 35 mL of toluene were added into a 100 mL Schlenk vial with electromagnetic stirring and the reaction was carried out at 85C for 4 h. After the temperature was lowered to room temperature, the toluene was removed. Wash with ether (3X10mL), draw dry to get white powder; white powder was recrystallized by dichloromethane/ether to get 0.448 g of colorless crystals of trans-dichlorobis(tri-O-tolylphosphine)palladium, the yield was 55. 9%.
