Abstract
1. The reaction of fluoromethyldimethylamine with polyfluoroketones leads to N,N-dimethylmethylenimmonium polyfluoroalcoholates which are capable of adding to perfluoroolefins to form polyfluoro-substituted alkoxyalkyldimethylamines. 2. Alkali metal perfluoroalcoholates add reversibly to perfluoroolefins to give β-perfluoroalkoxy carbanions which may be trapped by reaction with electrophilic reagents. 3. These results indicate that the perfluoroalkoxyhalogenation of higher perfluoroolefins proceeds by a nucleophilic mechanism.
