The chemical and industry development has made it possible to make changes in feedstock as well the creation of new materials, which can lead to facilitate the modernization of the society's lifestyle. However, progress has been accompanied by increased use of non-renewable sources and waste generation, drawing attention to environmental issues. Thus, the concept of green chemistry emerges to improve this request and, in this context, photo- and electrocatalytic approaches are gaining prominent positions as mediators of radical reactions.These approaches have some advantages when compared to traditional systems - Perhaps, the largest of them is the replacement of oxidizing and reducing reagents (most of them show high toxicity, difficult transportation and storage, and lead to a large waste generation) by the use of an electron current. In addition, this alternative synthesis methodology allows in situ generation of unstable reagents, by working in safe conditions and controlling the oxidation/reduction potential, thus allowing the development of highly selective processes.Therefore, this project aims to explore photochemical reactions promoted by visible light through photoredox catalysis mediated by transition metals and photo-organocatalysts.After, we intend to develop electrochemical and photoelectrocatalytic processes in batch or continuous flow for the synthesis and functionalization of heterocyclic systems. In this context, the stereoselective synthesis of nitrogenous systems will be evaluated through the combination of an electrochemical oxidation and an organocatalysed reaction. In addition, this proposal presents other perspectives, especially in the generation of radical species through the electrooxidation of carboxylic compounds, with subsequent scrambling, aiming at the synthesis of heterocyclic systems. To this end, nanostructured electrodes materials should be properly synthesized and characterized.
