N,N,N-Triethyl-N-[β-formyl-vinyl]-ammoniumperchlorat (1), a cationic α, β unsaturated aldehyde reacts with water at the carbonyl group. No addition was found to the olefinic double bound. This unusual behavior will be explained. The temperature dependence of the equilibrium constant measured by 1H NMR spectroscopy result in ΔH = —3.8 ± 0.5 kcal/Mol, ΔS30°C = —20 ± 3 e. u.
