Au(III) complexes for [18F] trifluoromethylation and methods for producing the same are disclosed. A gold complex comprises Au(CF3)2LR, wherein L comprises a solubility supporting ligand and R comprises an organic substituent. The Au(III) complex can be used to prepare a positron emitting isotope that can be used as tracers for positron emitting tomography (PET) scans.
Fluorination operates for good: A trifluoromethyl group is able to stabilize the title compound (see picture; Au yellow, C gray, F green, O red), which formed by low‐temperature treatment of [PPh4][Au(CF3)2] with BF3⋅OEt2. A trigonal environment is adopted by each molecule with aurophilic interactions with three near‐neighbors in a global triskelion arrangement.
