烯烃的感光光氧化反应已经得到了广泛的研究；它们代表了在特定部位引入氧气的方便方法。当含有单烯烃、二烯或多烯和敏化剂的充气溶液用可被敏化剂吸收的光照射时，形成含氧产物，其性质取决于底物的结构和初始光产物在反应条件下的稳定性。氢过氧化物对醇的易还原性增强了这些光氧化作用的合成用途。本章的内容仅限于具有一个或多个碳-碳双键的分子。
Sensitized photooxygenations of olefins have been extensively studied; they represent convenient methods for the introduction of oxygen at specific sites. When an aerated solution containing a monolefin, diene, or polyene, and a sensitizer is irradiated with light that can be absorbed by the sensitizer, oxygenated products are formed whose nature depends upon the structure of the substrate and the lability of the initial photoproducts under the reaction conditions. The ready reducibility of hydroperoxides to alcohols enhances the synthetic usefulness of these photoxygenations In this chapter, coverage is restricted to molecules with one or more carbon-carbon double bonds.
