The excellent surface catalytic potential of Fe3O4-OSO3H is utilized in the synthesis of symmetrically and unsymmetrically substituted urea derivatives via transamidation reactions. The scope of the surface catalysis is further extended in transamidation reactions of cyclic and acyclic amide derivatives, and in the amidation of fatty acids. In both transamidation and amidation reactions, the catalyst is reusable up to five times without significant loss in its activity.

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.

ZnO nanofluids were synthesized and utilized as a new reaction media in the preparation of amides via direct amidation of aliphatic carboxylic acids with primary amines under solvent-free conditions. High yields and good selectivity are achieved with this psudo-homogeneous catalyst, while the recovered nanoZnO was reusable.
