摘要：

Fluorine-18 exchange between BF4- or PF6- and the [18F]- labelled hexafluorides MoF6, WF6 or UF6 and between NbF6- or TaF6- and WF518F in acetonitrile is rapid at room temperature. Rapid 18F exchange is observed also between AsF6- and UF518F under identical conditions but is not observed between AsF6- and MoF518F or WF518F. No 18F exchange is observed between SbF6- and any of the three hexafluorides. On this basis SbF6- is the anion of choice in situations where a kinetically inert anion is required. © 1990.
