1,2-Bis(dichlorophosphino)ethane Chemical Properties, Uses, Production

Chemical Properties

Colorless to light yellow liqui

Uses

1,2-Bis(dichlorophosphino)ethane can be used as a precursor to synthesize ethylenebis(phosphonic dichloride).

reaction suitability

reaction type: Buchwald-Hartwig Cross Coupling Reaction
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: ligand

Synthesis

The synthetic route to 1,2-bis(dichlorophosphoryl)-ethane involves palladium-catalyzed reactions, ligand chemistry, and diphosphine ligands. It is synthesized from ethane in two steps: first, it is chlorinated by reaction with PdCl(CHCl) to form chloroethane (PEBE), which then reacts with PdCl(CHCl). The reaction product is then hydrolyzed to produce 1,2-bis(dichlorophosphoryl)-ethane.
