Vinylboronic anhydride pyridine complex Chemical Properties,Uses,Production

Uses

Vinylboronic anhydride pyridine complex can be used for Suzuki-Miyaura cross-coupling.

Uses

Reagent used for

  • Suzuki-Miyaura cross-coupling
  • Stereoselective synthesis via Palladium-catalyzed carboamination
  • Alkyl-connected 2-amino-6-vinylpurine (AVP) crosslinking agent to cytosine base in RNA
  • Kaiser oxime resin-derived palladacycle as a recoverable polymeric precatalyst in Suzuki-Miyaura cross-coupling reactions in aqueous media
  • Kinetic resolution of phosphoryl and sulfonyl esters of binaphthol derivatives via Pd-catalyzed alcoholysis of their vinyl ethers
  • Stereoselective isomerization of N-allyl aziridines into Z-enamines by using rhodium hydride catalysis
  • Kinetic resolution of axially chiral biaryl derivatives via palladium/chiral diamine ligand-catalyzed alcoholysis
  • Transition metal-catalyzed alkenylation of aziridines, cycloaddition and thermal rearrangement reactions
  • Intramolecular Heck reaction strategy for synthesis of functionalized tetrahydroanthracenes

Reagent used for Preparation of
