Various tetradentate and tridentate ligands such as salophane, bishydrazone, bisbenzimidazolyl pyridine and isonicotinohydrazide have been prepared. Transition metal complexes of these ligands with Cu, Ni and Fe have been further synthesized and characterized by UV–vis, IR, NMR and CHN analysis. Catalytic activity of the metal complexes was tested for the cross coupling of diarylchalcogenide with arylboronic acid in DMSO as solvent in presence of a base. These non-precious metal complexes catalysed cross coupling reactions smoothly in shorter reaction time compared to earlier reports with comparable yields.

A photcatalyst-free photoredox synthesis of diaryl selenides has been developed by coupling reaction of diselenides with aryldiazo sulfones. The reaction was accelerated under visible light irradiation without using a photocatalyst or photosensitizer. This approach facilitates the synthesis of diaryl selendes with a wide range of functional group tolerance.

A transition-metal-free 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 by-product isocyanuric acid can be easily isolated and recovered. Besides of arylboronic acids, aryl trifluoroborates and aryl trihydroxyborates salts are also able to perform this transformation. (Figure presented.).
Efficient heterogeneous copper-catalysed C–Se coupling of aryl iodides with symmetrical diselenides towards unsymmetrical monoselenides

A highly efficient heterogeneous copper(I)-catalysed C–Se coupling of aryl iodides with diaryl diselenides was achieved in dimethylformamide at 110 °C under neutral conditions by using a 10 mol% of bipyridine-functionalised MCM-41-supported copper(I) complex [bpy-MCM-41-CuI] as the catalyst and magnesium as the reductive reagent, yielding a variety of unsymmetrical diaryl selenides in good to excellent yields. This heterogeneous copper catalyst can be easily recovered by a simple filtration of the reaction solution and recycled at least seven times without significant loss of activity.
