Descrição geral

Potassium vinyltrifluoroborate is a versatile organometallic reagent used as a vinylating agent in the presence of palladium catalysts.

Potassium vinyltrifluoroborate is an air- and water-stable potassium organotrifluoroborate that can be utilized in coupling reactions under relatively mild conditions.

Aplicação

Organotrifluoroborate involved in:
  • Suzuki Miyaura cross-coupling reactions and polymerization reactions
  • Synthesis of photonic crystals
  • Synthesis of sensitizers for dye-sensitized solar cells
  • Mannich / diastereoselective hydroamination reaction sequence

Organotrifluoroborates as versatile and stable boronic acid surrogates.

Potassium Trifluoroborate Salts

Potassium trifluoroborates are a special class of organoboron reagents that offer several advantages over the corresponding boronic acids and esters in that they are moisture- and air-stable, and are remarkably compliant with strong oxidative conditions.

Potassium Organotrifluoroborates

These bench stable Potassium Organotrifluoroborates are useful for Suzuki-Miyaura cross-coupling reactions and have also been used for a variety of other C-C bond forming reactions. Importantly, these reagents are compatible with a wide range of functional groups and are stable to many commonly used and harsh reaction conditions.
