General description

Silver tetrafluoroborate (AgBF4) is used as a Lewis acid in organic synthesis. It is known to have a high affinity towards organic halides. It is employed in organic reactions like activation of acyl chlorides, nucleophilic substitution, rearrangement, cycloaddition, cyclization, ring expansion and oxidation.

Application

Displaces chloride from precious metal complexes used in the oxidation of alcohols by persulfate.
Provides a silver-ion template for improved macrolatamization of a linear dipeptide.
