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.
Zn in ionic liquid: an efficient reaction media for the synthesis of diorganyl chalcogenides and chalcogenoesters
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.

The reaction of bromomethyl-dibromo-indium(III), Br2InCH2Br with dialkylselenides, (RSeR2)-Se-1 (R-1 = CH3, R-2 = CH2C6H5; R-1 = C2H5, R-2 = CH2C6H5; R-1 = R-2 = CH2C6H5) afforded the corresponding dialkylselenonium methylide complexes of indium tribromide, (Br3InCH2SeRR2)-R-1, which were fully characterized by NMR spectroscopy and single crystal X-ray diffraction studies.
