A straightforward and efficient methodology is described to synthesize structurally diverse diorganyl selenides, sulfides, seleno- and thioesters by using commercially available Zn dust in ionic liquid. Excellent yields were achieved under neutral conditions at room temperature in a short time. The solvent/ionic liquid is reusable and exhibited higher performance as compared with organic solvents.

We report an efficient, fast, and environmentally friendly method for the synthesis of a wide range of thiolesters using stable diorganoyl disulfides and acyl chlorides, using CuO nanoparticles and [pmim]Br as the reductive system. This method gave good to excellent isolated yields of the desired products after only three minutes of microwave irradiation. Furthermore, by using the same green approach
