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.).

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.

Herein, we report the photochemical coupling of diphenyldiselenides with substituted phenylhydrazine hydrochloride without catalyst. The protocol was developed not only in presence of sunlight and UV light but also under thermal condition for comparison study. Moreover, ultrasound assisted new catalytic protocol was developed using Ni(II)/L-proline system in DMSO with the advantage of shorter reaction time compared to earlier reports. We have also developed a new C-Se cross coupling reaction where phenylselenyl chloride and arylhydrazine hydrochlorides were effectively coupled using developed catalytic system.
