procedure was proposed for synthesizing thioethers and selenide ethers fromanilines under solvent-free and transition-metal-free conditions. Thioethers were formed when anilines reacted with thiols under blue light-emitting-diode (LED) irradiation at room temperature without a photocatalyst. When reactions were performed using anilines and diselenides, the corresponding selenide ethers were obtained with
synthesized through CAr-Se bondformation using readily available copper(I) iodide as catalyst under mild reaction conditions (82 ˚C) from aryl iodides and diphenyl diselenide. In this coupling reaction, solvent acetonitrile acts as ligand for copper(I) iodide and no external ligand is required. Less reactive aryl bromides also provide the diaryl selenides in good isolated yields. copper catalyst - acetonitrile

method for the synthesis of arylselenides and aryltellurides has been established based on the oxidative cross-coupling between diorganyl dichalcogenides and aryl boronic acids. With trichloroisocyanuric acid as an oxidant, the reaction proceeded smoothly to afford the desired products in 45–97% yields at ambient temperature. Three reaction reagents used in this method are stoichiometric and the oxidation
We herein describe an alternative metal-free methodology for the synthesis of diorganyl selenides and tellurides mediated by Oxone®. The products were obtained in moderate to excellent yields by reactions of diorganyl diselenides or ditellurides with aryl boronic acids mediated by Oxone® with use of EtOH as the solvent. The methodology is applicable to a broad scope of diorganyl dichalcogenides and
