Theoretical studies provide insight into radiofluorination of non-activated electron-rich and sterically hindered 18F-arenes using a new class of adamantyl-based spirocyclic iodonium(iii) ylide precursors.
A process for fluorination of aromatic compounds employing iodonium ylides and applicable to radiofluorination using
18
F is described. Processes, intermediates, reagents and radiolabelled compounds are described.
