Sulfur-containing Salt-based Organophotoredox Catalysis

Salt-based organophotoredox catalysts exhibit strong oxidative properties, making them particularly effective for the oxidation of electron-rich substrates and for facilitating diverse chemical transformations via the reductive quenching cycle. While conventional salt-based organic photocatalysts are predominantly oxygen- and nitrogen-containing species, our group has recently developed three types of sulfur-containing salt-based organophotoredox catalysts. In this context, this review highlights recent advances in sulfur-containing salt-based organophotoredox catalysts and their applications in photoredox catalysis.
