Chitosan-grafted triethoxy-۲-mercapto benzimidazole-cuprous complex (CGTMBCC): An efficient heterogeneous nanocatalyst for N-arylation of N-heterocycles with aryl halides

Chitosan-grafted triethoxy-۲-mercapto benzimidazole-cuprous complex (CGTMBCC) was synthesized and its catalytic activity was examined in the Ullmann-type N-arylation of N-heterocycles with various aryl halides. The N-aryl adducts were obtained in good yields in DMF at ۱۱۰°C. Different techniques were employed to characterize the structure of CGTMBCC including XRD, TGA, FT-IR, FE-SEM, EDX, DLS, and AAS analysis. CGTMBCC could be reused for at least ۵ runs with no considerable decline in its reactivity.
