An Efficient Copper(I) Iodide Catalyzed Synthesis of Diaryl Selenides through C_(Ar)-Se Bond Formation Using Solvent Acetonitrile as Ligand

摘要

A wide range of diaryl selenides can be synthesized through C_(Ar)-Se bond formation using readily available copper(I) iodide as catalyst under mild reaction conditions (82 degC) from aryl iodides and diphenyl diselenide. In this coupling reaction, solvent acetonitrile acts as ligand for copper(I) iodide and no external ligand is required. Less reactive aryl bromides also provide the diaryl selenides in good isolated yields.
