Green Photochemistry: The Use of Microemulsions as
Green Media in Photooxygenation Reactions

Throughout academia and industry, green chemistry has recently become a burgeoning field of study. As early as 1998, a set of principles were established that illustrate the idea and definition of green chemistry. Of these principles, there has been an increasing interest in the use of “greener” solvents. In particular, the use of microemulsions of ethyl acetate and water, utilizing sodium dodecyl sulfate (SDS) and alcoholic co-surfactants as a reaction medium in photooxygenation reactions were of focus in this study. The reaction work-up for the synthesis of 5-hydroxyl-1,4-naphthoquinone was optimized as well as the ratio of components for the microemulsion to demonstrate the use of microemulsions as green media for photooxygenation reactions, with isolated yields of 36 – 88% through 4 hours of irradiation. Using this optimized procedure the synthesis of 5-amido-1,4-naphthoquinones was performed with moderate yields.
