In recent years, an environmentally friendly attitude toward chemistry and industrial processes has provided many challenges for the field of industry, academia and research. In this regard, a wide range of technologies have introduced new approach using recyclable catalysts, choosing non-hazardous solvents, finding new routes to the synthesis of compounds, modifying reaction selectivity, reduce waste materials, reduce the production of wastes and avoid wasting time and energy.
In view of the importance of this approach, new heterogenous catalysts based on isocyanurate and melamine were successfully prepared and investigated for the synthesis of cyanocinnamonitriles, nicotinonitrile and acridinedione derivatives. Furthermore, the oxidation of different benzyl alcohol derivatives to their corresponding benzaldehydes and subsequent Knoevenagel condensation under mild conditions was achieved by Cu(II) and magnetic nanoparticles on melamine-based catalyst. The notable advantages of this method are quantitative yields, easy and inexpensive purification route, easy separation from the reaction medium, easy and inexpensive purification of the products, easy separation from the reaction medium, recoverability and reused with negligible loss of its activity and well-aligned with the principles of green chemistry.
