Substituted oxiranes were readily transformed to the corresponding β-hydroxyhydroperoxides in good yields in ethereal H2O2 system with SnCl4 as a catalyst. Alternatively, the use of a stoichiometric amount of SnCl4 leads to a rearrangement of the oxiranes to aldehydes. A subsequent addition of ethereal H2O2 solution achieves primary gem-dihydroperoxides in moderate yields.
