2,4-Alkadienoic acid derivatives such as ester, amide, and nitrile were converted to the corresponding 4-oxo-2-alkenoic acid derivatives in good yields by the oxygenation with oxygen and triethylsilane in the presence of a catalytic amount of [5,10,15,20-tetra(2,6-dichlorophenyl)porphinato]cobalt(II) followed by acetylation.
