Thermosensitive core-shell microgel as a “nanoreactor” for catalytic active metal nanoparticles
Thermosensitive core-shell microgels can be used as “nanoreactors” for the immobilization of metal nanoparticles. The microgels consist of a polystyrene core and a network made ofExpand

We present a study on the catalytic activity of platinum nanoparticles immobilized on spherical polyelectrolyte brushes that act as carriers. The spherical polyelectrolyte brushes consist of a solidExpand
Stable Bimetallic Gold–Platinum Nanoparticles Immobilized on Spherical Polyelectrolyte Brushes: Synthesis, Characterization, and Application for the Oxidation of Alcohols
Metallic nanoparticles have recently received much attention as catalysts. In particular, gold nanoparticles have been shown to be excellent catalysts for oxidation reactions. Thus, in 1989 HarutaExpand
Catalytic Hydrogenolysis of Aryl Ethers: A Key Step in Lignin Valorization to Valuable Chemicals
Lignin is a robust biomacromolecule (or a polymer) that gives structural integrity to plants and constitutes 25–35% of the woody biomass. Lignin is inedible, barely used, and contains mostly aromaticExpand

Very fast, reversible, polyethylene (PE) chain transfer or complex-catalysed "Aufbaureaktion" describes a "living" chain-growing process on a main-group metal or zinc atom; this process is catalysedExpand
A Reusable Co Catalyst for the Selective Hydrogenation of Functionalized Nitroarenes and the Direct Synthesis of Imines and Benzimidazoles from Nitroarenes and Aldehydes.
The use of abundantly available transition metals in reactions that have been preferentially mediated by rare noble metals, for example, hydrogenations, is a desirable aim in catalysis and anExpand
The ligand-based quintuple bond-shortening concept and some of its limitations.
Herein, the ligand-based concept of shortening quintuple bonds and some of its limitations are reported. In dichromium-diguanidinato complexes, the length of the quintuple bond can be influenced byExpand
Towards f and d electron interactions in amido metal complexes
Abstract A short review of heterobimetallic amido complexes incorporating lanthanides and Group 9 or 10 metals is given. The use of bisaminopyridinato ligands allows the isolation of compounds withExpand
Highly active titanium-based olefin polymerization catalysts bearing bulky aminopyridinato ligands.
A series of titanium complexes have been prepared using either salt metathesis or amine elimination reactions. Reacting the potassium salt of Ap*H {Ap*H =Expand
Synthesis and Structure of Zirconium and Hafnium Polymerisation Catalysts Stabilised by Very Bulky Aminopyridinato Ligands
Mono(aminopyridinato) complexes of the type [ApM(CH(2)C(6)H(5))(3)] [M = Zr, Hf and Ap = aminopyridinate] were prepared by treating the three different sterically demanding aminopyridines with oneExpand
