Sulfamic acid: as a green and reusable homogeneous catalyst for peroxidation of ketones and aldehydes using aqueous 30 % H2O2

Sulfamic acid has been used as an active, low-cost and reusable solid catalyst for conversion of ketones and aldehydes to corresponding gem-dihydroperoxides using 30 % aqueous hydrogen peroxide at room temperature. The reactions proceed with high rates and excellent yields.
