Abstract

A simple and efficient method allows the synthesis of solutions of high-purity hydrogen trioxide (HOOOH), released in the low-temperature methytrioxorhenium(VII) (MTO)-catalyzed transformation of the ozonized polystyrene-supported dimethylphenylsilane. High-purity hydrogen trioxide solutions in diethyl ether, separated from the polymer and free of any reactants and by-products, can be stored at -20 °C for weeks. By removing the solvent in vacuo, HOOOH could be isolated in highly pure form or transferred to other solvents, thus significantly extending the research perspectives of HOOOH for novel applications.
