Vinyl benzoate compounds and enol carbamate derivatives are synthesized through coupling reactions and in the presence of a new nanomagnetic catalyst based on iron oxide nanoparticles. The novel nanomagnetic catalyst consisting of a copper (II) complex on silica-coated iron oxide nanoparticles (Fe3O4.SiO2) with good features and high performance. Both types of reactions were well performed by using a new nanomagnetic catalyst. In the first series of reactions, the reaction of beta-dicarbonyl compounds and an alkylbenzene such as toluene as reactants were used, and in the second series of reactions, beta-dicarbonyl compounds with N, N-dimethylformamide (DMF) were used as reactive substances. The results showed that in the presence of the nanocatalyst, the products were well synthesized.
