Chapter 4. Perspectives on the Use of Flow Systems to Carry Out Organic Photochemical Reactions

Organic photochemical reactions have been conducted using classic batch conditions for over a half century. Beginning in the 21st century, several efforts were conducted to develop reactions of this type, performed in a convenient, controllable and safe manner using flow micro reactors. This chapter describes the general methods used for flow micro photochemical reactions and some typical organic transformations that have been performed using this approach, including inter- and intra-molecular photocycloadditions, photocyclizations, photoadditions, photoisomerizations, photosubstitutions, photooxygenations, photorearrangements, heterogeneous photocatalytic reactions and photoinduced organometallic reactions.
