1,5-Bis(diphenylphosphino)pentane is used as a ligand for the cross coupling reactions. It is used in the manufacturing of glass bottle PTFE bottle, aluminum foil bag and in cardboard drum. combination of a 1,5-bis(diphenylphosphino)pentane ligand and the addition of N,N,N?,N?-tetramethylethylenediamine (TMEDA) as a co-catalyst are the key factors in obtaining the corresponding aryl nitriles with improved catalyst productivities and selectivities.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
1,5-Bis(diphenylphosphino)pentane is used as a ligand for the cross coupling reactions.
