Fig. 1. Influence of pH on the 125I-iodination (
) and 211At-astatination (
) of 4-chlorobenzeneboronic acid (1). RCYs determined by radio-HPLC analysis of the crude product. Standard conditions: (1) (0.25 mM), Cu(OTf)2pyr4 (10 mM), 1,10-phenanthroline (10 mM), [125I]NaI or [211At]NaAt (1–5 MBq), Tris buffer 0.5 M/DMF (85:15), 30 min, 100 μL, 23 °C, n ≥ 2.
