Nitronium tetrafluoroborate is an inorganic compound with formula NO₂BF₄. It is a salt of nitronium cation and tetrafluoroborate anion.^[1] It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO₃. As such, it must be handled under water-free conditions. It is sparsely soluble in many organic solvents.

Preparation

Nitronium tetrafluoroborate can be prepared by adding a mixture of anhydrous hydrogen fluoride and boron trifluoride to a nitromethane solution of nitric acid or dinitrogen pentoxide.^[2]

Applications

Nitronium tetrafluoroborate is used in organic synthesis as an electrophilic nitrating agent and a mild oxidant.^[3]
