An oxyallyl ion pair (3) is expected to be formed from PCA (1) by initial ionization of the enolate anion (2), which is followed by dissociation to the "free" oxyallyl intermediate (6). In TFE, a strong hydrogen bond between the solvent and the negative charge on the oxygen atom would be expected, leading in the extreme case to the 1,1,3,3,-tetrachloro-2-hydroxyallylium chloride ion pair and O-protonated oxyallyl species derived therefrom. Calculations on the unsubstituted oxyallyl prototype have suggested strong diradicaloid character rather than dipolar structures for these intermediates Perchloro substitution should stabilize the oxyallyl intermediate in any case. For ab initio calculations, see: [2a] Y. Osamura, W. T. Borden, K. Morokuma, J. Am. Chem. Soc. 1984, 106, 5112-5115.
