Alternative Metal-Free Synthesis of Diorganoyl Selenides and Tellurides Mediated by Oxone®

We herein describe an alternative metal-free methodology for the synthesis of diorganyl selenides and tellurides mediated by Oxone (R). The products were obtained in moderate to excellent yields by reactions of diorganyl diselenides or ditellurides with aryl boronic acids mediated by Oxone (R) with use of EtOH as the solvent. The methodology is applicable to a broad scope of diorganyl dichalcogenides and aryl boronic acids containing electron-rich, electron-poor, and sterically hindered substituents.
