Metal-free and site-selective α-C(sp 3 )–H oxidation of thioethers to access thioester derivatives

Key Points

• The strategy converts thioethers to thioester derivatives using a metal-free process.
• In this approach, water acts as the oxygen source for oxidation.
• The method utilizes an NCS-mediated reaction for site-selective editing of thioethers.
• Metal-free oxidation methods may lead to more sustainable chemical processes.
