NARAYANAPERUMAL, Senthil et al. Transition metal oxide nanopowder and ionic liquid: an efficient system for the synthesis of diorganyl selenides, selenocysteine and derivatives. J. Braz. Chem. Soc. [online]. 2010, vol.21, n.11, pp. 2079-2087. ISSN 0103-5053. http://dx.doi.org/10.1590/S0103-50532010001100008.
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.
