Silver tetrafluoroborate Silver tetrafluoroborate Silver tetrafluoroborate is an inorganic compound with the chemical formula AgBF. It is a white solid that dissolves in polar organic solvents as well as water. In its solid state, the Ag centers are bound to fluoride. Silver tetrafluoroborate is prepared by the reaction between boron trifluoride and silver oxide in the presence of benzene. In the inorganic and organometallic chemistry laboratory, silver tetrafluoroborate, sometimes referred to "silver BF-4", is a useful reagent. In dichloromethane, silver tetrafluoroborate is a moderately strong oxidant. Similar to silver hexafluorophosphate, it is commonly used to replace halide anions or ligands with the
Silver acetylide evolution of gaseous products and that its chemical formula is . In reality, it is a double salt with the silver salt it was produced from, usually silver nitrate. The anion of the parent compound acts as the oxidizer in the decomposition reaction. The detonation velocity of the mixture silver acetylide: silver nitrate is 3460 m/s. That of pure silver acetylide is 4000 m/s. Silver acetylide can be produced by passing acetylene gas through a solution of silver nitrate: The reaction product is a greyish to white precipitate. This is the same synthesis from Berthelot in which he first found
