Abstract:

Nowadays, there´s been growing the interest of some researches groups by nanosized metal particles due to their high catalytic activity compared to their bulk counterparts. The result from the heterogenic catalysis using nanosized metal particles is environmentally desirable. Furthermore, the solvent absence as well as the use of ultrasound make this methodology in accordance with the Green Chemistry protocols. Among the compounds nowadays synthesized, β-enaminones are the ones that present a great synthetic interest as building blocks or bioactives. This way, the aim of this study is the synthesis of β-enaminones catalyzed by nanoparticles of Fe2O3 through a clean methodology (Scheme 1).
