3-Arylselanyl- and 3-arylsulfanylindoles were prepared in EtOAc, by the reaction of indole with the diaryl dichalcogenide-trichloroisocyanuric acid (TCCA) reagent system. The products were efficiently and conveniently obtained, at room temperature and in

We have developed a protocol for the synthesis of diaryl thio-/selenoethers by the reaction of aryl chalcogenocyanates with electron rich arenes/hetero arenes via HFIP promoted C-H activation. The reaction produces chalcogenides in good to excellent yields under mild conditions without the need of a transition metal as a catalyst. The HFIP-mediated reactions tolerated a wide range of functional groups and set the stage for the synthesis of diversely decorated chalcogenides. A mechanism involving activation of the C-H bond through hydrogen bonding is proposed.
A selenium-based ionic liquid as a recyclable solvent for the catalyst-free synthesis of 3-selenylindoles

The ionic liquid 1-butyl-3-methylimidazolium methylselenite, [bmim][SeO2(OCH3)], was successfully used as solvent in the catalyst-free preparation of 3-arylselenylindoles by the reaction of indole with ArSeCl at room temperature. The products were obtained selectively in good yields without the need of any additive and the solvent was easily reused for several cycles with good results.
