چکیده مقاله :
In this article, recyclable Fe3O4@SiO2@FeCl3 was synthesized and entirely characterized by various techniques including XRD, FT-IR, SEM, EDX and VSM analysis. The catalytic ability of produced Fe3O4@SiO2@FeCl3 was studied in the aza-Michael reaction of diethyl amine and ethyl crotonate which lead to high yield of product. Also, this procedure was used to synthesize other derivatives resulted from different amines. Synthesized Fe3O4@SiO2@FeCl3 nanocatalyst has some great advantages such as easy preparation method, simple recovery and high efficiency.
