In chemical industries tetrafuoroboric acid and solvates thereof are used in the preparation of fuoroborate salts, in electroplating, in dipping solutions for surface treating of aluminum, as a pickling agent for hot rolled steel. Molten alkali-metal and ammonium fuoroborates are good solvents for metal oxides and c...

Disclosed is a dual-route process for the synthesis of 4-fluoro-3-hydroxybenzoic acid from 4-bromo-1-fluoro-2-methoxybenzene, offering significant improvements in yield, purity, and process simplicity. The first route employs copper(I) cyanide-mediated cyanation followed by a one-pot hydrolysis and demethylation, wh...
