Typical Properties

Product Description:
Potassium tetrakis(pentafluorophenyl)borate, often abbreviated as K-BArF or K-TPFPB, is a highly specialized and exceptionally stable anionic borate salt. It consists of a potassium cation and a bulky, weakly coordinating tetrakis(pentafluorophenyl)borate anion. This unique anion is renowned for its very low coordinating ability, meaning it interacts minimally with counter-cations, making it an ideal choice for stabilizing highly reactive cationic species. It is typically a white to off-white crystalline powder, soluble in various organic solvents, and is a crucial reagent in advanced synthetic chemistry.

Key Applications:

• Catalysis: Widely used as a co-catalyst or counterion in various polymerization reactions, especially in Ziegler-Natta and metallocene catalysis for polyolefin production. Its weak coordinating nature enhances the activity and stability of transition metal catalysts.

• Organic Synthesis: Employed in specialized organic reactions requiring a non-coordinating counterion to stabilize reactive intermediates, such as carbocations or transition metal complexes.

• Ionic Liquids and Electrolytes: Research applications in the development of novel ionic liquids and electrolytes due to its highly stable and weakly coordinating anion.

• Coordination Chemistry: Essential in the synthesis and study of new coordination compounds, particularly those with highly electrophilic or reactive metal centers.

• Polymer Science: Used in the preparation of specialized polymers and in research related to polymer modification and new materials development.
