This review summarizes the progress made in the last eight years on the synthesis and use in catalysis of polymer supported metal complexes obtained by co-polymerization of metal-containing monomers (MCMs) with suitable co-monomers and cross-linkers. These materials are divided into four important classes: microporous organic polymers, molecularly imprinted polymers (MIPs), macropouros organic polymers, poly Read More

With the ever-increasing demand for environmentally benign synthetic routes that can lead to desirable organic products, photocatalytic techniques have become more appealing than conventional synthetic methods because the former make it possible selective chemical transformations of various organic reactions with the help of sunlight as the source of the energy for the reactions. At the heart of photocatalytic chemical Read More

Over the past decade, metal nanoparticles as homogeneous catalysts have attracted extensive attention for organic transformations. The metal nanoparticles as supports enhance catalyst loadings and facilitate the catalyst recovery. As active parts, metal nanoparticles stabilized by polymers and dendrimers usually witness drastically improved catalytic efficiency. Chiral molecular ligands modified metal nanoparticles endow ch Read More

Here we present an overview of immobilized chiral catalysts and some successful examples for enantioselective process. The focus will put on the last general achievements regarding on the immobilization methods of chiral catalysts in asymmetric catalytic reactions, and finally give a perspective of future development.

Heterogeneous catalysts based on supported metal nanoparticles are commonly used in many industrially relevant catalytic reactions. This review examines the existing literature of several types of the supported-metal nanoparticle heterogeneous catalysts. Specifically, this review includes: (i) a brief overview of the catalysts from the immobilization of metal nanoparticles on mesoporous silica materials, oxide and carbon nanot Read More

Dendrimers are highly branched macromolecules with well-defined molecular structures and nanometer-scale dimensions. Dendrimer-supported catalysts behave homogeneously during the reaction, but most of them can be separated from the reaction medium via solvent precipitation. Their catalytic properties can be fine-tuned by adjusting the structure, size and shape of the dendrimers. In many cases, interesting dendrime Read More
