Organic Solid Acid/NaNO2: An Efficient System for the Oxidation of Urazoles and Bis-Urazoles under Mild and Heterogeneous Conditions

摘要

Various organic solid acids/NaNO2were used as effective oxidizing agents for the oxidation of urazoles and bis-urazoles to their corresponding triazolinediones under mild and heterogeneous conditions at room temperature with good-to-excellent yields.
