“Back to the Roofs”: The Solarchemical Production of Fine Chemicals With Sunlight

Three photochemical reactions were performed successfully under solar irradiation conditions: the photoacylation of quinones with aldehydes and the rose bengal sensitized photooxygenations of citronellol or 1,5-dihydroxynaphthalene. All reactions were easily performed on multigram to kilogram scales using cheap and commercially available starting materials, and yielded important key-intermediates for industrial applications.
