Abstract: The present invention is directed towards a process for the synthesis of compounds with the general formula (II) or their respective alkali metal salts by oxidation of compounds of general formula (I) with oxygen






in the presence of a heterogeneous catalyst containing a metal of group 10 of the periodic table of the elements,
wherein R1 and R2 and R3 are same or different and selected from H and C1-C6-alkyl, non-substituted or substituted with one or more moieties selected from COOH and O-R4 with R4 being selected from H and C1-C4-alkyl.
