carbanion 1a, generated by addition of fluorideion to perfluoroalkene 1, reacts efficiently with benzyl bromide and a range of related derivatives 3a–g and this provides methodology for the preparation of aromatic rings with large perfluoroalkyl substituents. Purification of the perfluoroalkylated products 4a–g was accomplished by selective extraction from the reaction medium by a perfluorocarbon fluid
