Publications related to Tuning the Chemoselectivity of Rh Nanoparticle Catalysts by Site-Selective Poisoning with Phosphine Ligands: The Hydrogenation of Functionalized Aromatic Compounds

Synthesis of hyperbranched polyarylethenes by consecutive C–H vinylation reactions

Kay Severin, Albert Ruggi, Anastasia Gitlina

A novel procedure for the synthesis of polyarylethenes is described. Consecutive C–H vinylation reactions of tetraphenylethene with a triphenylethenyl triazene give hyperbranched polyarylethenes of variable sizes. The vinylation reactions are mediated by a ...

Electro- and photochemical H-2 generation by Co(ii) polypyridyl-based catalysts bearing ortho-substituted pyridines

Rosario Scopelliti, Euro Solari, Albert Ruggi, Vincent Artero, Fiorella Lucarini

Cobalt(II) complexes featuring hexadentate amino-pyridyl ligands have been recently discovered as highly active catalysts for the Hydrogen Evolution Reaction (HER), whose high performance arises from the possibility of assisting proton transfer processes v ...

New Strategies for the Functionalization of Alkenes Exploiting Tethering Chemistry and Ring Strain

Bastian Antoine Rodolphe Claude Muriel

Amino alcohols, cyclopropanes and nitriles are privileged structural motifs found in the scaffold of natural products and bioactive compounds. In addition, they are versatile building blocks in organic chemistry. The development of new and increasingly eff ...

Identification of Isomeric Lipids by UV Spectroscopy of Noncovalent Complexes with Aromatic Molecules

Ruslan Yamaletdinov

The tremendous structural and isomeric diversity of lipids enables a wide range of their functions in nature but makes the identification of these biomolecules challenging. We distinguish and quantify isomeric lipids using cold ion UV fragmentation spectro ...

Palladium Catalysed Intramolecular Carbo-oxygenation of Propargylic Amines to Access 1,2-Amino Alcohols and alpha-Amino Ketones via in situ Tether Formation

Phillip Gulliver Dominic Greenwood

a-Amino ketones and 1,2-amino alcohols are important structural motifs in organic chemistry, that can be observed in natural products, pharmaceutically and bioactive compounds. For these reasons, they constitute privileged targets for the development of ne ...

Azide Radical Initiated Ring Opening of Cyclopropenes Leading to Alkenyl Nitriles and Polycyclic Aromatic Compounds

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel

We report herein a radical‐mediated amination of cyclopropenes. The transformation proceeds through a cleavage of the three‐membered ring after the addition of an azide radical on the strained double bond and leads to tetrasubstituted alkenyl nitrile deriv ...

Nickamine and Analogous Nickel Pincer Catalysts for Cross-Coupling of Alkyl Halides and Hydrosilylation of Alkenes

Xile Hu, Zhikun Zhang, Renyi Shi

CONSPECTUS: Ligand development plays an essential role in the advance of homogeneous catalysis. Tridentate, meridionally coordinating ligands, commonly termed pincer ligands, have been established as a privileged class of ligands in catalysis because they ...

Preventing Lignin Condensation to Facilitate Aromatic Monomer Production

Jeremy Luterbacher, Wu Lan

Lignin is the most abundant aromatic polymer in nature and as such is an attractive source of aromatic molecules. Efficient lignin utilization will also likely play a key role in the economic success and sustainability of biomass valorization schemes. Howe ...

Palladium-Catalyzed Carboamination of Allylic Alcohols Using a Trifluoroacetaldehyde-Derived Tether

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel, Ugo Jonathan Orcel

The selective palladium-catalyzed carboamination of allylic alcohols is reported on the basis of the use of an easily introduced trifluoroacetaldehyde-derived tether. Aminoalkynylation reactions were realized using alkynyl bromides and commercially availab ...
