Description

General description

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.

Application

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.
