Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A mesoporous TiO₂‐Fe₂O₃ mixed oxide material (MTF‐1E) with nanoscale porosity and a high BET surface area was synthesized using sodium dodecyl sulfate (SDS) as a structure‐directing agent. The material was characterized by powder XRD, high‐resolution TEM, N₂ sorption, and NH₃ temperature‐programmed desorption studies. The catalyst shows an excellent regioselectivity for the ring‐opening of epoxides with amines under solvent‐free conditions at room temperature for the synthesis of a series of β‐amino alcohols. It also showed a very high catalytic efficiency for the synthesis of benzimidazole derivatives in water. The catalyst can be recovered easily from the reaction medium and reused six times without a significant decrease in its catalytic activity and selectivity.</p> </abstract>
