Application

Lithium tetrakis(pentafluorophenyl)borate ethyl etherate can be used as:
  • A coordinating counter anion in electrochemical reactions along with transition metal catalysts to enhance their acidity or solubility.
  • A catalyst in the Baeyer-Villiger oxidation of cycloalkanones to obtain lactones in the presence of aqueous hydrogen peroxide and oxalic acid.
  • An activator in the synthesis of poly(norbornene ester)s.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Electrochemistry methods have been widely employed in the development of renewable energy, and involved in various processes, e.g. water splitting and oxygen reduction. Remarkable progress notwithstanding, there are still many challenges in further optimization of catalysts to achieve high performance.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
