The surface temperature on catalytically active magnetic nanoparticles (Fe2.2C@Ru) was estimated from their catalytic performances under magnetic induction. In different solvents, surface temperatures well-above the boiling point were determined.

This review is focused on iron-based homogeneous catalytic systems described so far for the reduction of carbonyl compounds (ketones and aldehydes) into alcohols via hydrosilylation. It begins explaining the basic concepts of the hydrosilylation reaction, addressing its main advantages and procedural differences with other common reduction methods, and highlighting its interest in organic chemistry. Then, the advances in the development of iron-based catalysts, as a more sustainable alternative to the traditional noble-metal catalysts, that have taken place to date are reviewed in depth. The revision of the different type of catalysts is followed by a profound discussion of the mechanistic proposals found in the literature for this type of catalysts.

We have synthesized a novel family of metal−organic chains based on 4-nitro-1H-pyrazole linker and zinc as metal center. We report the formation of these coordination polymers using hydrothermal routes with water as solvent. These materials display one-dimensional structures with major structural modifications from minimal synthetic variations. What is more interesting, we have carried out antitumor measurements, and we have related these properties with the structural networks. To the best of our knowledge, these materials constitute the first examples of polymeric structures for 4-NO 2pz ligands. NMR and MS spectrometry were used to verify the characterization of the metal complexes in solution to corroborate that these materials are present in the biological assays.
