Three different types of functionalized-CS were prepared and anchored with copper salts for use as the catalyst for the Ullmann C-X coupling reaction. The Schiff-basic chitosan supported copper complex (PCCS@CuI) exhibits the highest catalytic activity. The structure of the catalyst was characterized by FTIR spectroscopy, TG, XRD, SEM, EDS and XPS. This catalyst exhibited high applicability for the C-N and C-S coupling reactions, in which good to excellent yields were obtained. Its easy separation, good reusability and stability were notable.
