The Uses of NITROSONIUM TETRAFLUOROBORATE

Nitrosonium tetrafluoroborate is a nitrosating agent and oxidizer used in organic synthesis. It is also used to convert arylamines directly to diazonium tetrafluoroborates, which undergo the Balz-Schiemann reaction in situ to give high yields of aryl fluorides. Further, it is used as a catalyst for iodination of aromatics by iodide ion with air as oxidant, conversion of secondary amines to nitrosamines and in deamination of primary amides. It is involved in the conversion of arylhydrazines to azides. In addition to this, it reacts with ferrocene to prepare ferrocenium tetrafluoroborate.

The Uses of NITROSONIUM TETRAFLUOROBORATE

In the preparation of diazonium fluoborates.

The Uses of NITROSONIUM TETRAFLUOROBORATE

Nitrosyl tetrafluoroborate is an efficient nitrosating and diazotizing agent. It reacts with alcohols and secondary amines to yield alkyl nitrites and nitrosamines, respectively. It reacts with primary amines to yield diazonium tetrafluoroborates. NOBF₄ is also a mild oxidant and commonly used for single electron transfer oxidation.
