Cu(<scp>i</scp>)-mediated ¹⁸F-trifluoromethylation of arenes: Rapid synthesis of ¹⁸F-labeled trifluoromethyl arenes

Abstract

This report is concerned with an efficient, Cu(I)-mediated method for the radiosynthesis of [(18)F]trifluoromethyl arenes, abundant motifs in small molecule drug candidates and potential radiotracers for positron emission tomography. Three (18)F-labelled radiotracer candidates were synthesised from [(18)F]fluoride ions as proof of principle. The new protocol is widely applicable for the synthesis of novel radiotracers in high radiochemical yields.
