N-Fluoropyridinium triflate is an

fluorinating agent. It is a salt, consisting of the N-fluoropyridinium cation ([C5H5NF]+) and the triflate anion.[1] Related reagents include Selectfluor
, which is also an N-fluorinated salt.

N-Fluoropyridinium cations are not only electrophilic fluorinating agents (i.e., sources of "F+"), they are also one-electron oxidants.[2]
