Herein, we describe a valuable method for the introduction of the [18F]CF3 group into arenes with highly improved specific activity by the reaction of [18F]trifluoromethane with aryliodides or aryl boronic acids. This [18F]trifluoromethylation reaction is the first to be described in which the [18F]CF3 products are generated in actual trace amounts and can therefore effectively be used as PET tracers
Positronemissiontomography has emerged as the leading method for medical imaging with fluorine‐18 as the most widely used radioactive isotope. Here we report a semi‐automated method for the preparation of valuable [18F]trifluoromethylcopper, as well as its use for the radiosynthesis of [18F]trifluoromethylarenes and heteroarenes. Mild conditions of [18F]trifluoromethylation make this method particularly

the precursor and other reagents, as well as the limited availability of parent 18F sources of suitable reactivity ([18F]F– and [18F]F2). There is a high-priority demand for general methods allowing access to [18F]CF3-substituted molecules for application in pharmaceutical discovery programmes. We report the development of a process for the late-stage [18F]trifluoromethylation of (hetero)arenes from
