  Catalytic Decarboxylative Fluorination for the Synthesis of Tri- and Difluoromethyl Arenes

  摘要：

  Treatment of readily available alpha,alpha-difluoro- and alpha-fluoroarylacetic acids with Selecffluor 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 [F-18]labeling is demonstrated using [F-18]Selectfluor bis(triflate), a reagent affording [F-18]tri- and [F-18]difluoromethylarenes not within reach with [F-18]F-2.

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

In the absence of Ag(I)OTf, no reaction takes place at room temperature for both classes of substrates; this result demonstrates the beneficial role of silver(I) as a means to induce 18F-incorporation under very mild conditions.
