Silica Sulfuric Acid/NaNO2 as a Novel Heterogeneous System for the Oxidation of Urazoles under Mild Conditions.
ChemInform Vol. 34, No. 29
چکیده
Neat chlorosulfonic acid reacted with silica gel to give silica sulfuric acid (I) in which sulfuric acid functions immobilized on the surface of silica gel via covalent bonding. Urazoles and bis-urazoles can be readily converted to their corresponding triazolinediones with a combination of silica sulfuric acid (I), wet SiO2 and sodium nitrite in dichloromethane at room temperature.
