Abstract

Abstract A series of phosphazenium hydrofluorides, P 1 tBu⋅[18/19 F] HF, P 1 tOct⋅[18/19 F] HF, P 2 Et⋅[18/19 F] HF, and P 4 tBu⋅[18/19 F] HF, was synthesized. The radioactive phosphazenium [18 F] hydrofluorides were obtained by the one-step formation and trapping of gaseous [18 F] HF with the respective phosphazene bases. The [19 F] isotopomers were prepared from the corresponding phosphazene bases and Et 3 N⋅ 3HF. Under the design ...
