Nucleophilic reactions between cyclic 1,2-sulfites and chloride ions

When cyclic 1,2-sulfites are ring opened by chloride ion, the chlorohydrins are formed with low regio- and stereo-selectivity. The mechanisms involved in the process were investigated by measuring the stereochemical outcome of the reactions. The results showed that reversible inversion pathways (SN2 reactions) and a retention pathway (SN2i reaction) gave rise to the loss in ee in both the chlorohydrins and in the cyclic 1,2-sulfites.
