Applications
1,4-Bis(diphenylphosphino)butane is used in Suzuki reaction. It plays an essential role as a ligand in palladium(0)-catalyzed acylcyanation of arylacetylenes and deprotection of allyloxycarbamates. It acts as a ligand for alkylations, isomerization reactions and in organometallic chemistry. Further, it is used in Heck reaction, Negishi coupling and Sonogashira coupling. In addition to this, it is useful in organometallic chemistry.

Solubility
Soluble in chloroform. Slightly soluble in water

Notes
Incompatible with strong oxidizing agents.
