Reaction Steps

A mixture of 3 mmol of ethyl methacrylate, 4 ml of 2-propanol, 0.6 mmol of N-hydroxyphthalimide, 0.015 mmol of cobalt(II) acetate, and 0.045 mmol of acetylacetonatocobalt(III), and 1 ml of acetonitrile was stirred at 70° C. in an oxygen atmosphere (1 atm) for 5 hours. A gas chromatographic analysis of products in a reaction mixture revealed that ethyl 2,4-dihydroxy-2,4-dimethylpentanoate and α-hydroxy-α,γ,γ-trimethyl-γ-butyrolactone were formed in yields of 1% and 65%, respectively. The conversion rate from ethyl methacrylate was 85%.
