Abstract
Magnetic nanoparticles derived from iron oxide, for example, magnetite (Fe3O4) and maghemite (γ-Fe2O3), fulfill most of these requirements, and recent advances in their synthesis give access to size-controlled monodisperse particles. Hybrid magnetic materials have been synthesized from organic compounds and metal or metal oxide nanoparticles and examined as catalysts for the organic synthesis. When the reaction has been completed, the catalysts can be easily separated by simple external magnetic decantation.
Keywords: Hybrid magnetic materials, click chemistry, green chemistry, nanocatalyst, magnetic separation, nanomaterials.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners.

Electrochemical C-X bond formation
Conventional methods for carrying out carbon–X bond formation are typically conducted at harsh reaction conditions, and rely on expensive catalysts as well as the use of stoichiometric, and perhaps toxic, oxidants. In this regard, electrochemical synthesis has recently been recognized as a sustainable and scalable strategy for the construction of ...read more
