Nitronium tetrafluoroborate has been shown to be a versatile nitrating agent for nitrogen compounds, giving the corresponding N-nitro derivative when reacted with secondary aliphatic amines, an acyl aliphatic amine, a carbamate ester: a diacyl amine and primary amides.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications

Crystalline salt of the active species in the nitration of arenes. Enables nitration to be carried out in non-aqueous, non-acidic systems (typically in Sulfolane, A13466).

In acetonitrile solution, addition of the nitronium ion to alkenes, followed by Ritter reaction of the resulting carbonium ion with the solvent, leads to the nitroacetamide: J. Org. Chem., 36, 3641 (1971).

Has also been used for the oxidative cleavage of O-methyl ethers of aliphatic alcohols; e.g. benzyl methyl ether is cleaved to benzaldehyde: J. Org. Chem., 42, 3097 (1977). Ethylene dithioacetals are cleaved to carbonyl compounds: Synthesis, 273 (1979).
