CuO nano particles and [bmim]BF4: an application towards the synthesis of chiral β-seleno amino derivatives via ring opening reaction of aziridines with diorganyl diselenides

A series of chiral beta-seleno amino derivatives were synthesized via a ring opening reaction of different aziridines with diorganyl diselenides mediated by recyclable CuO nanopowder and an ionic liquid affording the corresponding products in good to excellent yields. The [bmim]BF4 ionic liquid acts as both promoter and reaction medium. Compared to the usual organic solvents the ionic liquid exhibited better performance with the advantage of its recyclability.
