Silver tetrafluoroborate weakly coordinating tetrafluoroborate anions. The abstraction of the halide is driven by the precipitation of the appropriate silver halide. 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
Caduceus as a symbol of medicine college, had carried before him a silver caduceus on a cushion, and later presented this artefact to the college, where it remains in the College's possession. This use was adduced by the medical historian (and primary apologist for the use of the caduceus in a medical context) Fielding Garrison to support his argument that the caduceus was used as a symbol of medicine as far back as the 16th century. However, as Walter Friedlander noted, "what Caius used was a non-specific herald's wand, rather than the caduceus of Hermes." In support of this assertion he quotes Caius's own words on
