Silver trifluoromethanesulfonate

It is a white or colorless solid that is soluble in water and some organic solvents including, benzene.

An early preparation method starts from the barium salt of trifluoromethanesulfonic acid (TfOH), from which the free TfOH is formed with dilute sulfuric acid, which is then neutralized with silver carbonate (Ag2CO3).

In an improved version by George Whitesides, dilute TfOH is reacted with silver(I)oxide (Ag2O), which produces AgOTf in 98% yield.

[4] It is used to prepare alkyl triflates from alkyl halides:[5] In coordination chemistry, the salt is also useful to replace halide ligands with the more labile triflate ligand.

For example, bromopentacarbonylrhenium can be converted to the more labile derivative using silver triflate:[6]
