A new catalytic protocol for the synthesis of selenoesters from aryl iodides and diaryl diselenides has been developed, where formic acid was employed as an efficient, low-cost, and safe substitute for toxic and gaseous CO. This protocol presents a high functional group tolerance, providing access to a large family of selenoesters in high yields (up to 97%) while operating under mild reaction conditions, and avoids the use of selenol which is difficult to manipulate, easily oxidizes, and has a bad odor. Additionally, this method can be efficiently extended to the synthesis of thioesters with moderate-to-excellent yields, by employing for the first time diorganyl disulfides as precursors.

This report describes a method for Ni-catalyzed intramolecular decarbonylative coupling, which enables the conversion of areneselenol esters to diaryl selenides. The inexpensive and readily available catalyst can be employed under mild reaction conditions for the construction of structurally diverse diaryl selenides, including heterocyclic and natural product derivatives.

A DTBP-promoted C-H selenation of aldehydes with diselenides under metal-free and solvent-free conditions is described. This system shows good functional group compatibility, functional groups including bromo, trifluoromethyl, chloro, amine and heterocycle-containing moieties including thiophene and furan are all tolerated by the reaction conditions employed. Both diaryl and dialkyl diselenides reacted smoothly with aldehydes to provide selenoesters in good to excellent yields. This journal is
