methodology has been developed to prepare 18F-labeled phosphorofluoridates and phosphonofluoridic acids via the [18F]F− nucleophilic substitution of imidazole-activated precursors. The efficient one-step 18F-fluorination affords stable products in the presence of Zn(Ⅱ) with high radiochemical yields and high molar activities. This 18F-fluorination method could be used to prepare various phosphorofluoridate
