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.
