Application

Boron trifluoride dihydrate can be used as:
  • An activator in Pechmann condensation to synthesize 4-methylcoumarin derivatives by the reaction between substituted phenols and methyl acetoacetate.
  • An initiator for the polymerization of benzoxazine.
  • A catalyst in the regioselective Fries rearrangement of phenolic esters to give hydroxyphenyl alkyl/aryl ketones.
  • A catalyst to prepare 8-hydroxymethyltricyclene acetate by the reaction between camphene and formaldehyde in the presence of methylene chloride-acetic anhydride solvent.
