Abstract

Operationally simple radiosynthesis and purification of [18F]fluoro-benziodoxole was developed starting from a cyclotron produced [18F]F- precursor, [18F]TBAF, and tosyl-benziodoxole. The synthetic utility of [18F]fluoro-benziodoxole was demonstrated by electrophilic fluorocyclization of o-styrilamides proceeding with high RCC (typically 50-90%) and high molar activity (up to 396 GBq μmol-1).
