Abstract
Chitosan biopolymer was functionalized with cysteine amino acid via trichloro-1,3,5-triazine-bridged agent. The magnetization process was done due to the treatment of functionalized chitosan with iron oxide nanoparticles. In the final nanocomposite (Fe3O4@T-CS@Cys@Ag+), thiol and carboxylate groups of cysteine were surrounded by silver ions. The catalytic activity of the prepared nanocomposite was studied in KA2 and A3 coupling reactions for the synthesis of propargylamines.
