Transition metal oxide nanopowder and ionic liquid: An efficient system for the synthesis of diorganyl selenides, selenocysteine and derivatives

Abstract

We have developed an efficient method for the synthesis of diorganyl selenides and β-seleno amines using Zn, catalytic amounts of ZnO nanopowder, as a catalyst and ionic liquid as a recyclable solvent. This ZnO/ionic liquid system shows high efficiency in catalyzing these transformations with the formation of the desired products in high yields. © 2010 Sociedade Brasileira de Química.
