Abstract
We report a method for labeling arylvinyltrifluoromethanes with carbon-11 (t1/2 = 20.4 min) as representatives of a new radiolabeled chemotype that has potential for developing radiotracers for biomedical imaging with positron emission tomography. Treatment of (E)-arylvinyl(phenyl)iodonium tosylates (1a-1k) with [11C[CuCF3 gave the corresponding [11C]arylvinyltrifluoromethanes ([11C]2a-[11C]2k) in high radiochemical yields (90-97%) under rapid (2 min) and mild (60 °C) conditions.
