tetrafluoroborate

Tetrafluoroborate is an anion with the chemical formula BF4^-, consisting of a boron atom centrally coordinated by four fluoride ions in a tetrahedral arrangement. It is commonly paired with various cations, such as alkali metals or organic cations, to form salts. Tetrafluoroborate salts are widely used in organic synthesis and electrochemistry due to their stability, low nucleophilicity, and ability to dissolve in both organic and aqueous solvents. They serve as electrolytes in non-aqueous batteries, ionic liquids, and electroplating baths. Additionally, tetrafluoroborate is utilized as a counterion in catalysis and in the stabilization of reactive intermediates during chemical reactions.
