Unsensitized photo-oxidation of the furan (1) yields the acrylate (4) as the major product. This reaction and that with singlet oxygen proceed through completely independent routes. Oxidation of (1) by triplet oxygen has also been studied using AIBN as a free-radical initiator; in addition to (4) the product (12), incorporating the isobutyronitrile radicals, was formed.
呋喃(1)的未敏化光氧化产生丙烯酸酯(4)作为主要产物。该反应和与单线态氧的反应通过完全独立的途径进行。还已经使用AIBN作为自由基引发剂研究了三重态氧对(1)的氧化;除了(4)以外,还形成了结合有异丁腈基团的产物(12)。
