Synthesis of Aryl Fluorides from Potassium Aryltrifluoroborates and Selectfluor^® Mediated by Iron(III) Chloride

Dedicated to Prof. Paul Knochel on the occasion of his 59^th birthday

Abstract

The synthesis of fluorinated arenes by the iron-mediated fluo­rination of potassium aryltrifluoroborates with Selectfluor^® and potassium fluoride is described. The fluorination reaction uses commercially available reagents and without requiring the addition of exogenous ligands. Fluorinated compounds were obtained in moderate to good yields under mild reaction conditions.

Key words

fluorination - aryl fluorides - potassium aryltrifluoroborates - iron - Selectfluor^® - potassium fluoride
