The nucleophilic 211At-labeling of aryliodoniumylides was investigated and proved significantly more efficient than radioiodination. Reaction is rapid at room temperature with electron-poor activated substrates whereas heating and addition of the radical scavenger TEMPO was essential in the case of deactivated precursors to reach high RCY and molar activity.

The 211At-labeled compound, 4-[211At]astato-L-phenylalanine, is one of the most promising amino acid derivatives for use in targeted alpha therapy (TAT) for various cancers. Electrophilic demetallation of a stannyl precursor is the most widely used approach for labeling biomolecules with 211At. However, the low acid-resistance of the stannyl precursor necessitates the use of an N- and C-terminus-protected
