colourless crystalline solid
Nitronium Tetrafluoroborate is used in the preparation of triazolyl glycoside as galectin-3 inhibitors.
Nitronium Tetrafluoroborate is used as a electrophilic nitrating agent; mild oxidant; hydride and halide abstracting agent.
Nitronium Tetrafluoroborate is soluble in sulfolane, acetonitrile; slightly soluble in nitromethane. Compared with NO2
+BF4
-,
NO2
+PF6
- has much higher solubility in organic solvents.
Due to its hygroscopic nature, Nitronium Tetrafluoroborate (NO2 +BF4 -) should be stored
and used under anhydrous conditions. Commercial NO2
+BF4
- often contains varying amounts of
NO+BF4
-. Removal of the NO+ from NO2
+BF4
- is difficult. Therefore, pure nitronium
tetrafluoroborate should be prepared directly from urea-treated purified HNO3.
