While iron oxide nanoparticles enjoy rich applications as catalysts, solid supports, and magnets, the use of their reduced and much less stable counterparts in the oxidation state zero is still at an infant stage. This minireview summarizes recent developments in the area of such metallic iron(0) nanoparticles. A major emphasis is laid on the controlled synthesis of small particles (mostly < 50 nm) and their application as ca Read More

With the rapid development of materials science, the noble metal nanoparticles (NPs) with tunable size and shape have attracted much attention because the tailored nanoparticles affected the catalytic performance tremendously. Besides the noble metal nanoparticles, the easily available transition metal nanoparticles such as Ni-NPs have also been utilized as catalysts recently for various kinds of reactions. In this review, w Read More

This review will intend to cover the main examples on the use of soluble and supported iridium metal nanoparticles as effective catalysts for hydrogenation of different substrates in conventional reaction medium, such as water, organic solvents, and ionic liquids. Some aspects involving the synthesis of these nanocatalysts will be also discussed in details.

Even if rhodium is one of the rarest and the most costly metals, this noble metal has found many catalytic applications, particularly in hydrogenation and hydroformylation reactions owing to its specific catalytic properties. Tremendous research activities are thus carried out by the scientific community for the development of novel rhodium-based catalysts. This interest for rhodium catalysts concerns also the moder Read More

This review describes some of the fascinating advances in the field of chemoselective hydrogenation of α,β-unsaturated aldehyde to unsaturated alcohol over nanomaterials that have emerged in recent years. The examples described are categorized into three main sections, according to the research approach applied, including the size/shape/composition control of the metal nanoparticle catalysts, the employment of novel n Read More

Ionic liquids (ILs) are excellent media for the generation and stabilisation of metallic nanoparticles (NPs). Their ionic character coupled with 3-D structural pre-organisation in the liquid state, serves to direct the growth of transition metal NPs generated in situ, and to subsequently protect and stabilise them. Until now, many different NPs have been successfully synthesised within these media, however much attention has been Read More

This review deals with synthetic potential and utility of benzoylacetonitrile in the synthesis of pyridine derivatives. The reactions are subdivided into groups that cover the synthetic methods of pyridine derivatives from benzoylacetonitrile e.g. self condensation, Friedlander reaction, Michael Addition reaction, addition to enaminones, reaction with enamino-nitriles or enamino-esters, and one-pot three component reactions.
