Zinc trifluoromethanesulfonate or zinc triflate is the zinc salt of trifluoromethanesulfonic acid.

It is commonly used as a Lewis acid catalyst, e.g. in silylations.

[1] A white powder, zinc triflate is commercially available, though some workers have experienced inconsistent results with zinc triflate from different sources.

[2][3] If desired, it may be prepared from reacting trifluoromethanesulfonic acid with zinc metal in acetonitrile,[4] or with zinc carbonate in methanol:[5]
