We report a fluoride-initiated coupling reaction between trifluoromethylarenes and allylsilanes to access allylated α,α-difluorobenzylic compounds. This method's utility is demonstrated through a 30 mmol scale reaction, a sequential allylation/derivatization protocol and multiple examples of site-selective trifluoromethylarene allylation. Initial mechanistic studies suggest a base-induced single electron transfer pathway is responsible for the high efficiency and selectivity of this novel C-F substitution process.

Method for preparing compounds of the formula (III) by reacting compounds of the formula (II) with a) an alcoholate or b) an alcohol R1-OH and a base in the presence of a Cu-containing catalyst and of a ligand, where X1-5 are independently of one another either carbon or nitrogen, or in each case two adjacent X1R1, with i=1?6, linked by a formal double bond together O, S, NRH or Nrl. The ligands preferably employed are acyclic and/or cyclic oligo- and polyglycols, oligo- and polyamides or oligo- and polyamine glycols of the general formula (IV) k is an integer >0 and n is an integer >1; X and Y are independently of one another O, NH or NR1.
