The presented falling‐film microreactor is suited for the generation and reaction of singlet oxygen for the photo‐oxygenation of olefins and allows for the first time conversions on a preparative scale. Due to the short holdup the concentration of the explosive endoperoxide is low in the whole reactor system and the endoperoxide is reduced to the final product immediately after leaving the reactor. The results show the feasibility of this reaction although the process is not yet optimized.
