摘要

This is the first report for C–Se bond formation involving the reaction of aryl halides with arylboronic acid and selenium powder to synthesis of unsymmetrical diaryl selenides in the presence of CuI as a homogeneous catalyst. A wide range of aryl halides react with various substituted groups under optimal conditions to provide the desired unsymmetrical diaryl selenides with good to high yields. Also, the same reactions were investigated in the presence of M-MCF@Gua-Cu as a reusable magnetic nanocatalyst under optimal conditions. The M-MCF@Gua-Cu catalyst allows for simpler (easy work-up) and greener methodology. In addition, the advantages of the presented method include the use of arylboronic acid/Se as a safe and cost-effective arylselenating system, the simplicity of operation, and green and cheap solvent.
