In the presence of enolizable carbonyl compounds, hemiaminals of fluoral and related polyfluoroaldehydes behave as equivalents of fluoroalkyl iminium compounds and provide β-polyfluoroalkyl β-dialkylamino ketones, which are easily transformed, under acidic conditions, into β-polyfluoroalkylenones.
Trifluoroethylidenation of compounds with activated methylene groups

α-trifluoromethyl iminium trifluoroacetates 5 can be prepared from N-oxides 4 and used in situ or after isolation. Condensation occurs with carbonyl activated methylene groups to give useful β-trifluoromethyl vinyl ketones 8.
