while SnCl(4) and trimethylsilyl triflate promote formation of peroxides. Lewis acid-promoted reactions of silylated hydroperoxyacetals furnish silylated hydroperoxides, which can be deprotected to homologated hydroperoxides. Hydroperoxyketals undergo Lewis acid-mediated allylation to furnish 1,2-dioxolanes via attack of hydroperoxide on the intermediate carbocation. Lewis acid-mediated cyclization

Lewis acid-mediated reaction of monoperoxyacetals with silylketeneacetals (SKAs) provides an efficient approach to 3-peroxyalkanoates. Propionate SKAs react with aliphatic peroxyacetals to furnish 3-peroxy-2-methyl alkanoates with modest anti-selectivity. Although acetate and thioacetate SKAs are less reactive, the latter react with unsaturated peroxyacetals to furnish peroxyalkenoates and -alkadienoates
