Abstract [18 F] 2-Fluoroethyl tosylate ([18 F] FEOX, X= Ts) is widely used for labeling radiotracers for positron emission tomography (PET). Little work has been reported on syntheses of other [18 F] 2-fluoroethyl arylsulfonates ([18 F] FEOX) that bear a less electron- rich aryl group, even though these might offer enhanced reactivities. Thus, a series of novel [18 F] FEOX (X= benzenesulfonyl, brosyl, nosyl, 3, 4-dibromobenzenesulfonyl) were ...
