Advances in the photoredox catalysis of S(VI) compounds

The S(VI) compounds, mainly sulfonamide functional groups are widely used in medicinal and agro-chemistry for almost a century. Other molecules with S(VI) centre, namely sulfones, sulfoximines, sulfonimidamides, sulfonimidates are presently receiving tremendous interest in several areas including medicinal and synthetic organic chemistry. Despite numerous methods following the traditional pathways have been developed to synthesize these molecules and their further organic transformations, currently, light driven photoredox catalytic techniques have occupied front row due to their close connections with green and sustainable chemistry. This review discusses the preparations and synthetic applications of S(VI) centre bearing molecules via photoredox catalysis in detail to date.
