Abstract
Abstract:
In the present study, a new magnetically recyclable nanocatalyst, Fe3O4@SiO2@(CH2)3-en-
SO3H/H2SO4, was prepared through the immobilization of sulfonated ethylenediamine on the silicacoated
magnetite nanoparticles. The catalyst was fully characterized by several physicochemical techniques,
including FT-IR, FESEM, TEM, EDS, VSM, XRD and TGA. The resultant nanocatalyst was
then utilized in the green synthesis of 2,3-dihydroquinazolin-4(1H)-ones via the cyclocondensation
reaction of various aldehydes and ketones with anthranilamide in refluxed EtOH. Short reaction times,
high product yields, environmentally friendly reaction conditions, simple operation and reusability of
the catalyst are important features of the present procedure. The catalyst can magnetically be recycled
and reused several times without notable loss in the activity.
