Abstract:
Pentafluoroethyllithium generated from pentafluoroethane and n-butyl lithium added to selected imines, which were activated using BF3 etherate, furnished α-pentafluoroethylated amines and, unexpectedly, depending on the stoichiometry of the reactants, bis(pentafluoroethyl)fluoro-N-(isopropyl)diisopropyliminium borate, whose molecular structure was confirmed by X-ray diffraction.
