Application
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.
Packaging
500ml high pressure aluminum cylinder equipped with a stainless steel valve according to DIN 477-1.
Other Notes
For 743704-250g-EU packaging: 500 mL of aluminium cylinder equipped with brass valve.
For 743704-250g-EU: outlet fitting: DIN 477-1 no. 1, Z742160 or Z742161 are the recommended regulators.
