A novel and efficient heterogeneous CuSO4 nanoparticles (CuSO4 NPs) immobilized on CM-cellulose/polyaniline (CuSO4NPs@CMC/PANI) composites were prepared via one-pot and one-step interfacial oxidative polymerization of aniline with sodium CM-cellulose (CMC) as soft template and CuSO4 as catalyst. The in situ formed CuSO4 NPs were dispersed uniformly and firmly on the resultant composites and stabilized by complexation with hydroxyl groups (OH), carboxylate groups (COO–), nitrogen atoms, and delocalized π-π conjugate benzenoid and quinoid moieties of CMC/PANI composites. The morphol., composition, and structure of the as-fabricated composites were systematically characterized by XPS, transmission electron microscopy (TEM), SEM (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform IR spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric anal. (TGA), and derivative thermogravimetry (DTG) techniques. The CuSO4NPs@CMC/PANI composites were successfully applied as catalysts in aldehyde-alkyne-amine (A3) coupling reactions, A3-cycloisomerization tandem reactions, and Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. All reactions proceeded smoothly and afforded the desired products in excellent yields. Moreover, no significant decrease in catalytic ability was observed in A3 model reaction after 15 recycles, indicating CuSO4NPs@CMC/PANI composites exhibited easy separability and high reusability. Tolerance of wide scope of substrate, excellent catalytic activity, easy operation, recycling of catalyst, and environmental benign are the salient features of these catalytic process.
