Abstract
Ultrasound is shown to increase the rate of the TEMPO-mediated oxidation of methyl alpha-D-glucopyranoside or sucrose in the presence of stoichiometri c amounts of sodium hypochlorite in basic aqueous medium. The reaction can then occur without the usually necessary sodium bromide, showing that ultra sound acts at the level of the formation of the nitrosonium ion, the active oxidizing species in the catalytic cycle.
