Photooxygenation reactions involving singlet oxygen (O) are utilized industrially as a mild and sustainable access to oxygenated products. Due to the usage of organic dyes as photosensitizers, these transformations can be successfully conducted using natural sunlight. Modern solar chemical reactors enable outdoor operations on the demonstration (multigram) to technical (multikilogram) scales and have subsequently been employed for the manufacturing of fine chemicals such as fragrances or biologically active compounds. This review will highlight examples of solar photooxygenations for the manufacturing of industrially relevant target compounds and will discuss current challenges and opportunities of this sustainable methodology.
光氧化反应涉及单线态氧 (O)，被工业界用作温和且可持续的含氧产物制备方法。由于有机染料可用作光敏剂，因此这些转化可以使用自然光成功进行。现代太阳能化学反应器能够在示范（多克）到技术（多千克）规模上进行户外操作，并随后用于制造香精或生物活性化合物等精细化学品。本文综述将重点介绍用于工业相关目标化合物制造的太阳能光氧化反应实例，并讨论该可持续方法的当前挑战和机遇。
