Synthesis and properties of metal trifluoride complexes with amide-functionalised tacn macrocycles and radiofluorination of [GaF3(L1)] by 18F/19F isotopic exchange.

Dalton Transactions
Three amide-functionalised tacn macrocyclic derivatives (tacn = 1,4,7-triazacyclononane) are reported, two tris-amide derivatives, L1 containing three -CH2C(O)NHPh pendant arms, L2 containing three -CH2CH2C(O)NHiPr pendant arms, and one mono-amide, L3 ...

Development of radiosynthesis methods for 18F-labelled radiopharmaceuticals : General considerations and production of a dopamine transporter radioligand [PDF]

, 2011
Positron emission tomography (PET) is a molecular imaging technique that utilises radiopharmaceuticals (radiotracers) labelled with a positron-emitting radionuclide, such as fluorine-18 (18F).

Late-stage (radio)fluorination of alkyl phosphonates via electrophilic activation

Nature Communications
Constructing organic fluorophosphines, vital drug skeletons, through the direct fluorination of readily available alkyl phosphonates has been impeded due to the intrinsic low electrophilicity of PV and the high bond energy of P═O bond.

Automated radiosynthesis of [18F]fluoromannitol for clinical research on a commercially available trasis allinone radiosynthesizer

EJNMMI Radiopharmacy and Chemistry
Background Infections pose a significant risk to immunocompromised individuals, and accurate, efficient diagnosis remain challenging. Current imaging methods like MRI and FDG PET lack pathogen specificity which complicate diagnosis and lead to overuse of
