Design, Synthesis and Visible-Light-Induced Non-Radical Reactions of Dual-Functional Rh Catalysts
K. Tanaka and Y. Nagashima report about the design, synthesis and visible-light-induced of non-radical reactions.
In visible photocatalysis, a catalyst absorbs photons from a visible-light source and undergoes an electronic excitation to a higher energy state. This excited-state photocatalyst can then interact with organic substrates to initiate a wide range of reactions, which are otherwise much more challenging under conventional thermal conditions. In recent years, photocatalysis has emerged as a powerful tool in organic synthesis, revolutionizing the way chemists design and execute a large number of transformations.
A single transition-metal complex that performs both visible-light absorption and chemical transformation is an ideal photocatalyst. Currently, such transition-metal catalysts are mainly limited to radical mechanisms. In this report, the group of Professor Ken Tanaka from the Tokyo Institute of Technology (Japan) explores this topic and finds a powerful solution, which could open the way to new avenues in organic photocatalysis.
