A simple method for the reduction of Schiff bases using biosynthesized nickel oxide nanoparticles

An innovative and simple approach for the reduction of aldimines to the corresponding secondary amines was described using biosynthesized nickel oxide nanoparticles as heterogeneous catalyst and ammonium formate as the hydrogen donor. This catalytic transfer hydrogenation method was highly efficient and helps to synthesize amines with remarkable yields and without any coarse environment.
