2-Ethyl-5-methylthiophene was subjected to liquid-phase oxidation with molecular oxygen in glacial acetic acid in the presence of cobalt acetate and sodium bromide. The effect of the concentrations of the substance undergoing oxidation, cobalt acetate, and sodium bromide on the oxidation was investigated. The chief reaction product — 2-acetyl-5-methylthiophene — was isolated. A difference in the reactivities of 2-ethylthiophene and 2-ethyl-5-methylthiophene is demonstrated.
