Abstract
The system thiourea dioxide–hydrogen peroxide is found to effectively hydroxylate coumarin in aqueous solutions. The hydroxyl radical reacting with coumarin is shown to result from decomposition of the complex thiourea dioxide–H2O2. The obtained data are compared to the results of investigation of the reactions occurring in the system thiourea dioxide–H2O2 with terephthalic acid.
