Abstract

A novel heterogeneous catalyst (Fe₃O₄@CS@Schiffbase@Cu) is developed by generating the Cu(II) Schiff base complex on the Fe₃O₄-chitosan surface. The structural and morphological characteristics of the catalyst is confirmed by all physicochemical techniques. A low catalyst loading (1.1 mol% Cu) of the immobilized Cu(II) Schiff base complex shows its catalytic activity for A³ coupling reaction of Aldehyde, Alkyne, and Amines under microwave irradiation. The catalyst was proven very active for a wide variety of propargylamines syntheses using different substituted aromatic aldehydes, secondary amines, and phenylacetylene under optimized conditions. The recyclability of the catalyst was efficient even after six cycles with a 95% efficiency.
