چکیده
Recently, graphene and graphene oxide have attracted enormous interest in the development of composite materials and catalysts, due to their remarkable physical, chemical and electrical characteristics, including a very high specific surface area. The synthesis of graphene nanosheets on alarge scale from graphite is a well-established route, where graphene oxide is an intermediate product. The presence of oxygen-carrying functionalities in graphene oxide facilitates their dispersion in water and polar solvents, as well as interrupts the regular p electron distribution. These unique characteristics makes graphene oxide a potent material for the immobilization of various nanoparticles, polymeric composites and catalytic activities [1].Facile separation and recovery of the catalysts is a significant issue, while imobilization on nanopatricles is a favorable approach. Among different nanoparticles which are used as supports, magnetic graphene oxide (MGO) has attracted interests because of its high surface area, stability, easy separability and unique potential technical applications.Multi-component reactions (MCRs) are defined as one-pot processes that three or more substrates combine either simultaneously, or through a sequential addition procedure that does not require any change of solvent. Quite recently MCRs have gained importance especially in the total synthesis of natural products, and medicinal heterocyclic compounds, because of their simplicity, higher yield of the products, and lower reaction times[2].Herein a synergic approach has been presented for performing MCR in the presence of MGO supported catalysts.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
