β¦ Synopsis
tSF-labelled cytosine-and uracil-nucleosides are synthesized starting from their unprotected parent nucleosides by reaction with acetylhypofluorite in acetic acid in an overall radiochemical yield of 20 and 30% respectively.

## Abstract The radiosyntheses of 5β(4β²β[^18^F]fluorophenyl)βuridine **[^18^F]β11** and 5β(4β²β[^18^F]fluorophenyl)β2β²βdeoxyβuridine **[^18^F]β12** are described. The 5β(4β²β[^18^F]fluoroβphenyl)βsubstituted nucleosides were prepared via a Stille crossβcoupling reaction with 4β[^18^F]fluoroiodobenzen
