fluoroborate

[‚flu̇r·ə′bȯr‚āt]
(inorganic chemistry)
Any of a group of compounds related to the borates in which one or more oxygens have been replaced by fluorine atoms.
The BF4- ion, which is derived from fluoroboric acid, HBF4. Also known as fluoborate.

Gennarom, Reductive Cleavage of Carbon-chlorine Bonds at Catalytic and Non-catalytic Electrodes in 1-Butyl-3-methylimidazolium tetrafluoroborate, Phys.
Next, the sections were incubated with 0.3% Triton X-100 for 15 min to allow membrane penetration, followed by washing with PBS; then, the sections were incubated with 2 mol/LHCl for 30 min, followed by washing; and the sections were then incubated with sodium tetrafluoroborate. The sections were blocked by serum at room temperature for 30 min and probed using diluted antibodies at 4[degrees]C overnight.
In our previous report, the efficiency of room-temperature ionic liquid, l-butyl-3-methyl imidazolium tetrafluoroborate (bmimB[F.sub.4]) in epoxy/CNT system cured with anhydride was investigated using CNT in the powder form [26], An improvement of the CNT dispersion and the electrical conductivity was observed by using the CNT previously ground with the ionic liquid.
By using 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim] + [BF4]-), an ionic liquid, as a morphology-controlling agent, the anatase Ti[O.sub.2] nanocrystals enclosed by exposed {0 0 1}-facets were obtained via the release of [F.sup.-] ions from [[B[F.sub.4]].sup.-] anions that stabilized the {0 0 1}-facets, leading to the preferred growth of these facets [16].
The sample solutions were ~[10.sup.-4]M in distilled anhydrous solvents, and dry tetra(n-butyl)ammonium tetrafluoroborate (TBATFB) (Aldrich) was used as the supporting electrolyte at 0.1 M.
This synthesis uses a visible light-promoted insertion of vinyl isocyanides 87 with diphenyliodonium tetrafluoroborate 88 at room temperature to prepare six multisubstituted ring-fluorinated, trifluoromethylated, and fluoroarylated isoquinoline derivatives 89.
(2011) studied the fire performance and decay resistance of wood treated with the quaternary ammonia compounds didecyl dimethyl ammonium chloride (DDAC) and didecyl dimethyl ammonium tetrafluoroborate (DBF), both independently and paired with the common fire retardants monoammonium phosphate (MAP), diammonium phosphate (DAP), and ammonium sulfate (AS), to determine if the preservatives showed fire retardancy or showed decay-resistant properties by themselves.
The breakthrough, he said, was to use an ionic fluid called ethyl-methyl-imidazolium tetrafluoroborate, mixed 50-50 with water.
6] that for state of tetrafluoroborate ion in coordination bonds in case of two-charging metals the electron-donor ability (basicity) of Am has the paramount importance.
