ELECTRFLUORATION EN POSITION BENZYLIQUE DANS LE SULFOLANE

Article abstract of DOI:10.1016/S0022-1139(00)80368-1

The use of sulfolane as a solvent instead of acetonitrile in the electrofluorination of benzylic derivatives 1, (R=H, Cl) gives greater yields of benzylic fluorides 2, since the formation of acetamide byproducts 4 is prevented.However, the parallel fluorination of the aromatic nucleus is not avoided under these conditions.
