Abstract

PERIN, Gelson et al. Clean and atom-economic synthesis of a-phenylselenoacrylonitriles and a-phenylseleno- a,b-unsaturated esters by knoevenagel reaction under solvent-free conditions. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.4, pp.857-862. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532005000500027.

Um método simples e eficiente foi desenvolvido para a síntese de a-fenilselenoacrilonitrilas e ésteres a-fenilseleno-a,b-insaturados através, respectivamente, da reação one-pot de aldeídos com fenilselenoacetonitrila ou acetato de (fenilseleno)etila na presença de um catalisador em suporte sólido (KF/Al2O3), sem o uso de solvente.

Keywords : solvent-free reaction; Knoevenagel condensation; phenylselenoacrylonitriles.
