Popis: Scandium triflate-catalyzed N-[18F]fluoroalkylation of aryl- or heteroaryl-amines with [18F]epifluorohydrin ([18F]2) was investigated. This reaction is mild and provides one-step access to N-[18F]fluoroalkylated aryl- or heteroaryl-amines, which are used for positron emission tomography imaging. Use of 2,2,2-trifluoroethanol as a cosolvent improved the re-action efficiency. The use of (S)- or (R)-[18F]2 produced the corresponding enantiomeric N-[18F]fluoroalkylated anilines.
