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