CA 2369829

The invention relates to a method for oxidizing organic substrate by using 1O2. According to the inventive method, organic substrates that react with 1O2 are mixed with 30-70 % H2O2 in water, in an organic solvent or in a mixture thereof in the presence of a lanthanide as the catalyst. H2O2 is catalytically decomposed to water and 1O2 and is then oxidized to the corresponding oxidation products.

La présente invention concerne un procédé pour oxyder des substrats organiques avec <1>O2. Selon ce procédé, les substrats organiques réagissant avec <1>O2 sont mis dans de l'eau, dans un solvant organique ou dans un mélange des deux, en présence d'un lanthanide en tant que catalyseur, avec du H2O2 à 30-70 %. Après la décomposition catalytique de H2O2 en eau et en <1>O2, l'oxydation conduit à la formation des produits d'oxydation correspondants.
