1,2-Butadiene Chemical Properties, Uses, Production

Uses

1,2-Butadiene can be used as a reagent:

  • To synthesize useful β-borylallylsilanes building blocks by reacting with various achiral silylboranes via Pd-catalyzed asymmetric silaboration reaction.
  • In the enantioselective diboration reaction in the presence of palladium catalyst and Lewis base ligand.
  • 3-methyl-4-methyleneisocoumarin via formation of ortho-thallated benzoic acid in the presence of thallium trifluoroacetate and palladium catalyst.

Definition

ChEBI: Buta-1,2-diene is a butadiene and a member of allenes.
