Soluble in N,N-dimethyl formamide.


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.


Store at room temperature. Keep away from oxidizing agents.
