Herein we report, a new, simple and mild procedure for N-benzylation and N,N-dibenzylation of anilines 12 through the reaction of aniline derivatives and benzyl bromide at 60 °C in EtOH in the presence of 13 catalytic amounts of magnetic Fe3O4 nanoparticles functionalized with hexamethylenetetramine 14 (Fe3O4@SiO2@Propyl-HMTA). The title compounds were formed in high purity and their structures 15 characterized by spectral analysis. The results also showed that the magnetic nanoparticle catalyst had 16 significant advantages including, simplicity of preparation, heterogeneity, stability and recyclability. 17 Moreover, the catalyst was characterized by various methods, such as FT-IR, SEM, VSM, TEM, 18 TGA and XRD, after the reaction to compare with its structure before reaction.
