NITRONIUM TETRAFLUOROBORATE Usage And Synthesis

Chemical Properties

colourless crystalline solid

Uses

Nitronium Tetrafluoroborate is used in the preparation of triazolyl glycoside as galectin-3 inhibitors.

General Description

Nitronium Tetrafluoroborate is used as a electrophilic nitrating agent; mild oxidant; hydride and halide abstracting agent.

Solubility in organics

Nitronium Tetrafluoroborate is soluble in sulfolane, acetonitrile; slightly soluble in nitromethane. Compared with NO2 +BF4 -, NO2 +PF6 - has much higher solubility in organic solvents.

storage

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.
