Photoredox catalysis with visible light.
The increasing need for more efficient synthetic methods and sustainable processes can be seen as a major driving force for new inventions; it also stimulates the creative rethinking of known concepts, which, in turn, will lead to the development of innovative chemistry. For example, starting from the challenge to mimic and understand enzymatic transformations, organocatalysis has now become an...
متن کاملSelective difluoroalkylation of alkenes by using visible light photoredox catalysis.
A visible light-induced process for selective difluoroalkylation of unactivated alkenes has been developed. The choice of base is crucial for governing the chemoselectivity of the process to produce difluoroalkylated alkanes and alkenes.
متن کاملBatch to flow deoxygenation using visible light photoredox catalysis.
Herein we report a one-pot deoxygenation protocol for primary and secondary alcohols developed via the combination of the Garegg-Samuelsson reaction, visible light-photoredox catalysis, and flow chemistry. This procedure is characterized by mild reaction conditions, easy-to-handle reactants and reagents, excellent functional group tolerance, and good yields.
متن کاملVisible-light photoredox catalysis in flow.
Photoredox catalysts have recently been utilized as powerful tools for synthetic chemists to exploit the energy gained by the absorption of low-energy light within the visible spectrum to initiate a variety of organic transformations. The development of methods based on the single electron transfer properties of photoredox catalysts, particularly in the last several years, has represented a par...
متن کاملAsymmetric catalysis activated by visible light.
Visible light driven organic chemistry has sparked much excitement over the last several years. This review summarizes recent progress in combining visible light activation with asymmetric catalysis, processes that are either mediated by photoinduced electron or energy transfer. The tasks of photoactivation and asymmetric catalysis are typically accomplished by dual catalyst systems but several...
