Ketones and aldehydes undergo facile hydroperoxidation on treatment with aqueous hydrogen peroxide (30%) in the presence of 10 mol% stannous chloride dihydrate in acetonitrile under very mild conditions to afford the corresponding gem-dihydroperoxides in satisfactory yields.

SrCl2·6H2O has been shown to act as an efficient catalyst for the conversion of aldehydes or ketones into the corresponding gem-dihydroperoxides (DHPs) by treatment with aqueous H2O2 (30%) in acetonitrile. The reactions proceed under mild and neutral conditions at room temperature to afford good to excellent yields of product.

Application of trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane as an efficient oxygen source has been explored in the epoxidation of trans-chalcones. The reactions proceed under mild conditions at room temperature in alkaline solution to afford the corresponding epoxides in excellent yields.
