      abstract     = {A convenient method for the preparation of hitherto unknown
                      ([F-18]fluorophenyl)acetylenes ([F-18]FPAs) using the
                      Seyferth-Gilbert homologation is reported. The novel
                      building blocks were efficiently prepared from easily
                      accessible [F-18]fluorobenzaldehydes by using the
                      Bestmann-Ohira reagent. High radiochemical yields and
                      excellent radiochemical purities were achieved within only
                      20 min of reaction time; 2- and 4-[F-18]FPAs were applied to
                      prepare radiofluorinated heterocycles by using different
                      cycloaddition and cross-coupling reactions. Additionally,
                      these building blocks were used to prepare three novel PET
                      tracers. Thus, an artificial radiofluorinated protected
                      amino acid [F-18]10, a COX-2-specific ligand [F-18]14, and a
                      PSMA-selective inhibitor [F-18]16 were obtained in high
                      radiochemical yields.},
