Sodium borohydride was used as the foundation of hydrogen for the reduction of imine. Facile and tidy transformation for synthesizing secondary arylamines through one-pot reductive amination of aniline, using aldehyde catalyzed by the reinforced nickel and poly(vinyl sulfonic acid) on mesoporous carbon CMK-3 (Ni/PVSA/CMK-3) as a novel acid-metallic bi-practical heterogeneous catalyst. Various characterization tactics including FT-IR, XRD, TG, Wager, SEM, TEM, DRS-UV and AAS had been employed to reveal the partnership between catalyst aspect and catalytic performance. The response was performed at area temperature, in a brief reaction time, without the by-products. This method has several advantages such as for example, eco-friendly (used drinking water as solvent), moderate to high yields, straightforward work-up treatment and catalyst filtered easily and reused without evident loss of activity. Reaction results demonstrate that the optimized Ni/PVSA/CMK-3 catalyst shows comparable catalytic performance because of the nickel metals and the acidic dynamics of polymer in mesopore stations of CMK-3.
