N-Fluoropyridinium triflate was labelled with 18F proceeding through N-trimethylsilylpyridinium triflate and [18F]F2 diluted to 1% in Ne. A typical experiment afforded this new fluorine-18 transfer reagent with up to 46% radiochemical yield. The specific activity of 18F-labelled N-fluoropyridinium ...
