Dissolution behaviour and activation of selenium in phosphonium based ionic liquids

Abstract

The dissolution behaviour of grey selenium in phosphonium based ionic liquids (ILs) has been investigated for the first time by ³¹P and ⁷⁷Se nuclear magnetic resonance (NMR) experiments. The investigations evidence the formation of trialkylphosphane selenides which can serve as a selenium reservoir in the subsequent formation of metal selenides.
