Abstract

Treatment of readily available α, α-difluoro-and α-fluoroarylacetic acids with Selectfluor under Ag (I) catalysis led to decarboxylative fluorination. This operationally simple reaction gave access to tri-and difluoromethylarenes applying a late-stage fluorination strategy. Translation to [18F] labeling is demonstrated using [18F] Selectfluor bis (triflate), a reagent affording [18F] tri-and [18F] difluoromethylarenes not within reach with [18F] F2.
