Potassium fluoroborate is obtained by treating potassium carbonate with boric acid and hydrofluoric acid. Fluoroborates of alkali metals and ammonium ions crystallize as water-soluble hydrates with the exception of potassium, rubidium, and cesium. Fluoroborate is often used to isolate highly electrophilic cations. Some examples include: 2).

Silver tetrafluoroborate is an inorganic compound with the chemical formula AgBF 4. It is a white solid, although commercial samples often are gray, that dissolves in polar organic solvents as well as water.

Like N-haloamides, nitronium tetrafluoroborate (NO2 BF 4) is employed with a nucleophile to effect overall addition of a nitro group and the nucleophile to the double bond of an alkene.

Tetrafluoroborate is the anion BF 4−. This tetrahedral species is isoelectronic with many stable and important species including tetrafluomethane, CF 4, and the closely related anion perchlorate, ClO 4−. It arises by the reaction of fluoride salts with the Lewis acid BF 3 or by treatment of tetrafluoroboric acid with base.

2023年1月31日 · Tetrafluoroborate (BF 4 −) has long been used as a spectator counter anion. Herein, we report an unprecedented salt metathesis between a variety of BF 4 − salts and a series of organoboronic acids yielding the corresponding organotrifluoroborates.

2009年4月21日 · Silver tetrafluoroborate is a chemical compound of silver, fluorine, and boron. It is commonly used in inorganic and organometallic chemistry to replace halide anions or ligands with the weakly-coordinating tetrafluoroborate anions.
