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.

Efficient nonenzymatic decomposition of guanidine derivatives with high structural and functional diversity into anilide products is achieved in the presence of PdII/Cu(II) carboxylates/CO, relying on a dual C-N bonds cleavage strategy. In this decomposition process, the cooperative action of PdII species, Cu(II) carboxylates, and CO provides not only the N-acylating agents but also an initiator to trigger this C-N bonds cleavage sequence. The current results indicate that PdII/Cu(II) carboxylates/CO system provides a convenient and practical method for highly selective cleavage of unreactive C-N single bonds.

Seven betaines were prepared by condensation of N,N'-diphenylamidines with malonic acid derivatives. The amidines were made via a multistep synthesis, starting from their corresponding fatty acids. Malonyl chloride and dipentachlorophenyl phenylmalonate, two derivatives of malonic acid, were obtained from malonic acid and benzyl chloride, respectively. Most of the products were characterized by IR, UV, 1H and 13C NMR. Biological assays of the synthesized betaines revealed their good antibacterial and antifungal activities against the Pseudomonas aeruginosa, Bacillus subtilis and Mucor ramannianus and an activity against Candida albicans.
