Nitrosonium tetrafluoroborate, 98%, Thermo Scientific Chemicals

Description

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.
