In the presence of a catalytic amount of simple copper salt, the reaction of arylboronic acids with diphenyl diselenide and ditelluride was accomplished without any additive to afford the corresponding unsymmetrical diarylselenides and tellurides in good yields.

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

A highly efficient heterogeneous ruthenium(III)-catalyzed reaction of diaryldiselenides with alkyl halides was achieved in DMF at 100 °C in the presence of 2 mol% of an MCM-41-immobilized bidentate nitrogen ruthenium(III) complex [MCM-41-2N-RuCl3] and zinc, yielding a variety of unsymmetrical diorganyl selenides in good to excellent yields. This new heterogeneous ruthenium catalyst can easily be prepared

interconversion and due to their biological activities. In this contribution, we report the synthesis of a series of these important substances in a mixture of water and dimethyl carbonate (20/1 proportion) using potassium thio- or selenocyanates salts and organic bromides. The key to the effectiveness of the reaction is a chalcogen bond interaction between a selenonium salt catalyst and the organic substrate
