A metal-free aerobic selective sulfoxidation photosensitized by Rose Bengal or solid-supported Rose Bengal has been developed. The reaction utilizes visible light as the driving force and molecular oxygen as the oxidant. Among the advantages of the developed method are its high efficiency and selectivity, extremely simple operation and workup procedure, and minimal waste generation.
