This review focuses on recent advances that have been made in conducting synthetically useful organic photochemical reactions by using microflow reactors. Attention is given to the utilization of this technique in the “scale-up” of a variety of photochemical processes including intermolecular photocycloadditions, intramolecular photocycloadditions and photocyclizations, photoadditions, photoreductions, photoisomerizations, photosubstitutions, photooxidations, photorearrangements, and heterogeneous photocatalytic reactions. In many examples, the use of the microflow method is compared to those carried out in batch systems. Finally, advantages and disadvantages of microflow photoreactions along with the possible employment of this approach to scale-up industrial photochemical processes are discussed.

这篇评论集中在通过使用微流反应器进行合成有用的有机光化学反应方面取得的最新进展。应注意在各种光化学过程的“放大”中使用该技术，包括分子间光环加成，分子内光环加成和光环化，光加成，光还原，光异构化，光解，光氧化，光重排和多相光催化反应。在许多示例中，将微流方法的使用与在批处理系统中执行的方法进行了比较。最后，讨论了微流光反应的优缺点以及该方法可能用于扩大工业光化学工艺的可能性。
