Multicomponent Synthesis of Heterocycles

Nanosized sulfated titania was prepared by a sol−gel hydrothermal process. X-ray diffraction (XRD), transmission electron, and scanning electron micrographs (TEM and SEM), FT-IR specific surface area, and BET N2 adsorption were employed to characterize the properties of the synthesized sulfated TiO2. The results indicate that both anatase and rutile TiO2 are obtainable. This prepared sulfated titania showed high catalytic activity in direct amidation of fatty acids as well as benzoic acids with various amines under solvent-free conditions.
