Reactivity of stable trifluoroacetaldehyde hemiaminals. 1. An unexpected reaction with enolizable carbonyl compounds.
In the presence of enolizable carbonyl compounds, hemiaminals of fluoral and related polyfluoroaldehydes behave as equivalents of fluoroalkyl iminium compounds and provide beta-polyfluoroalkyl beta-dialkylamino ketones, which are easily transformed, under acidic conditions, into beta-polyfluoroalkylenones.
