An In(OTf)(3)-catalyzed N-benzylation of amines utilizing benzyl alcohols through direct C-O bond activation has been reported. The reaction was performed in water without any base, additive, ligand or inert gas protection to afford the chem-selective mono- or bis-alkylated aromatic amines in good to excellent yields.

A series of HSO4- functionalized ILs was synthesized and used as efficient, green, and metal-free catalysts for benzylation. Notably, the catalytic system has wide substrate scopes and the ionic liquid catalysts were applied to investigate three different types of nucleophiles to give the desired benzylation products with moderate to excellent yields.
