Abstract
Chitosan decorated copper nanoparticles catalysts (CSCuNPs) were synthesized via reduction methods utilizing green protocol. The CSCuNPs catalysts were tested for the synthesis of quinoline derivatives utilizing one-pot multicomponent reaction (MCR) under ultrasonic irradiation. The best catalyst (Cu-CS-NPs) that provided good conversion reaction yield and high turnover frequency (TOF) was characterized using FTIR, TGA, XRD, TEM and XPS techniques. Generalization of the scope of the proposed catalytic process was studied using different aldehydes. Excellent products yield and high TOF in even shorter reaction time (~5 min) was attained. Recyclability performance of the catalyst over five times re-use without detectable loss in product yield was recorded. The current method is green process utilizing environmentally benign catalyst and considered to be promising sustainable protocol for the synthesis of fine chemicals.
