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.
2,4-烯二烯酸衍生物,如酯、胺和腈,在有[5,10,15,20-四(2,6-二氯苯基)卟啉]钴(II)的催化量存在下,经过氧气和三乙基硅烷的氧化反应,转化为相应的4-氧-2-烯酸衍生物,并且产率较好,随后进行乙酰化。
