Abstract

Heterogeneous metal-catalyzed chemical conversions with a recyclable catalyst are very ideal and challenging for sustainable organic synthesis. Bipyridyl-Mo(IV)-carbon nitride (CN-K/Mo-Bpy) was prepared and characterized by FTIR, XRD, SEM, EDS, XPS and ICP-OES. Heterogeneous CN–Mo-Bpy catalyst can be applied to the direct amination of nitro compounds and boric acid, thus constructing various valuable diarylamines in high to excellent yields with a broad scope and good functional group tolerance. It is worth noting that this heterogeneous catalyst has high chemical stability and can be recycled for at least five times without losing its activity.
