Catalytic and Efficient Oxidation of Urazole Derivatives to Their Corresponding Triazolinediones Using Ammonium Nitrate and Metal Hydrogen Sulfate as Catalyst

摘要

Catalytic oxidation of a variety of urazoles to the triazolinediones via combination of NH4NO3 in the presence of a catalytic amount of aluminium hydrogen sulfate has been developed at room temperature in dichloromethane.
