Efficient Ullmann C–X coupling reaction catalyzed by a recoverable functionalized-chitosan supported copper complex

Author affiliations

Abstract

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.
