Synthesis of chitosan-stabilized copper nanoparticles (CS-Cu NPs): Its catalytic activity for C-N and C-O cross-coupling reactions and treatment of bladder cancer

Herein, we report the synthesis of copper nanoparticles at ambient conditions using biopolymer, chitosan, as a protecting and stabilizing agent and hydrazine as a reducing agent. The obtained nanoparticles (CS-Cu NPs) were characterized using XRD, FT-IR, FE-SEM, EDS, TEM and UV–Vis spectroscopy. This nanocomposite was utilized as an efficient heterogeneous nanocatalyst for the aryl and heteroaryl C–N and C–O cross coupling reactions with...
