摘要

Abstract The present study describes the synthesis, characterization, and catalytic activity of Cu (II) containing nanosilica triazine dendrimer (Cu (II)-TD@ nSiO 2). The prepared catalyst was characterized by FT-IR, TGA, elemental analysis, UV–vis, FE-SEM, TEM, XPS and ICP- OES techniques. The Cu (II)-TD@ nSiO 2 has been used as an efficient catalyst for the preparation of various benzimidazoles, benzothiazoles, symmetrical bis-benzimidazoles ...
