Aryltrimethylammonium trifluoromethanesulfonates as precursors to aryl [ 18 F]fluorides: Improved synthesis of [ 18 F]GBR‐13119 [PDF]

, 1989
Aromatic nucleophilic substitution of various trimethylammonium trifluoromethanesulfonates with [ 18 F]fluoride has been evaluated. Fluorinations were studied over a temperature range of 45–165°C, with decay corrected yields ranging from 20–80%.
