1,4-Bis(diphenylphosphino)butane Usage And Synthesis
Chemical Properties
white to light yellow crystal powde
Uses
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.
Purification Methods
Recrystallise it from EtOH [Trippett J Chem Soc 4263 1961]. [King J Coord Chem 1 62 1971, Tolman Chem Rev 77 313 1977.]
