Applicazioni

Tetraethylammonium tetrafluoroborate is used as a phase transfer catalyst in organic synthesis. It finds application as an electrolyte additive in the capillary electrophoretic separation of polyphenols found in grape seed extracts. It is also used to prepare other tetrabutylammonium salts in aqueous solutions. It is involved in the synthesis of conducting poly(thiophenes).

Note

Hygroscopic. Incompatible with strong oxidizing agents.

Electrolyte for electro-organic synthesis, e.g. in the o- and p- hydroxylation of simple aromatic ketones, acids and esters by anodic oxidation in TFA: J. Chem. Soc., Chem. Commun., 262 (1975). In CH3CN, the products are the corresponding o- and p-acetamido compounds (cf Ritter reaction).

Use as a supporting electrolyte and F- source for electrochemical fluorination has also been reported: J. Electroanal. Chem., 43, 318 (1973).
