When boron trifluoride is reacted with sodium hydride, trifluorohydroxoborate sodium is produced. This reaction usually proceeds in the medium of ester.
The equation for the reaction is:
BF3 + NaH → Na[BF3H]
When the reaction takes place in the presence of anhydrous aluminium chloride and aromatic solvents, sodium chloride is produced as a by-product. This prevents reaction of sodium hydride and has to be removed from its surface. It reacts with aluminium chloride and dissolves in the aromatic solvent.
To minimise decomposition of the sodium hydride, the reaction temperature should be kept below 68°C
