Tetrafluoroborate is the anion BF 4. This tetrahedral species is isoelectronic with tetrafluoroberyllate (BeF … 展开

The popularization of BF 4 has led to decreased use of ClO 4 in the laboratory as a weakly coordinating anion. With organic compounds, especially amine derivatives, ClO 4 forms potentially explosive derivatives. Disa… 展开

Despite the low reactivity of the tetrafluoroborate anion in general, BF 4 serves as a fluorine source to deliver an equivalent of fluoride. The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known e… 展开
