Synthesis of Diorganyl Selenides Mediated by Zinc in Ionic Liquid

A new approach for the synthesis of diorganyl selenides is described. By using economically attractive zinc dust in BMIM-BF4, a series of diorganyl selenides were efficiently achieved in excellent yields, under neutral reaction conditions. Compared to the usual organic solvents, BMIM-BF4 exhibited higher performance with the advantage to be reused up to five successive runs.
