Anatase phase TiO2- nanoparticles (TiO2 NPs) used as a heterogeneous and highly efficient catalyst for the synthesis
of formamides and acetamides by reacting the structurally diverse amines with formic acid and acetic anhydride or
acetic acid, respectively, under solvent-free conditions at room temperature. Chemoselectivity, mild and heterogeneous
conditions, clean work-up and high reaction yields make this method practical for organic transformations.
Keywords: TiO2- nanoparticles, N-formylation, N-acetylation, formamides, acetamides, solvent-free.
