A method of reacting chemicals comprising the exposure of the reactants to ultrasound and electrochemical energies in the presence of a metal or metal salt and hydrogen peroxide. HO. radicals are efficiently formed and react with a carbon-based reactant to form a carbon radical which then reacts with other reactants or may dimerize. The invention regenerates the metal ions and may be performed using no special facilities. Increased product yield was achieved for a number of hydroxylation reactions.

Why it's free to use
- Filed September 1, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 1, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 1, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
