Abstract Oxosulfonylation is a difunctionalization protocol where oxo and sulfonyl groups are introduced in one step to construct ketosulfones N ‐acylsulfonamides from simple readily accessible reagents. The development of oxosulfonylation methods has gained significant attention due their importance organic medicinal chemistry. This review article provides brief concise overview the current status latest methodologies using green oxidant sources for reactions developed last two decades. magnified image

Abstract The upsurge in interest the development of methodologies for synthesis sulfur‐containing compounds via use visible‐light has been established as a sustainable tool organic chemistry. Particularly, mediated C−S bond formation gained popularity due to its operational simplicity, minimized by‐products, easy handling, mild reaction conditions, etc. Photochemistry not only provides way synthesize complex molecules but also ability overcome many challenges which are difficult attain by conventional thermal pathways. Owing biological importance compounds, present review focused on under metal‐free conditions visible‐light. objective current is bring out unearthing collection regarding photoredox catalysis. For better understanding, categorized according mode reactions viz , difunctionalization alkenes and alkynes, C−H functionalization, radical cyclization. All each sections described with selected examples proper explanation proposed mechanism.

Herein, we reported the heterogeneous photocatalytic C–H alkylation of indoles with diazo compounds using graphitic carbon nitride (g-C3N4) as photocatalyst. The reaction was carried out under a simple operation and mild conditions. In addition, catalyst found to be stable reusable after five cycles. photochemical proceeds via an intermediary radical, which is generated from through visible-light-promoted proton-coupled electron transfer (PCET) process.
