The oxidation of methacrylic acid esters to pyruvic acid esters was carried out with aqueous H2O2 in CH3CN in the presence of a catalytic amount of chromium compounds such as Cr(III)(acac)3, chromium salts, and chromic acid.The oxidation of methyl methacrylate in the presence of chromic acid and triethylamine (1:1) gave an 82 percent conversion with a 72 percent selectivity to methyl pyruvate at 40 deg C for 20 h.
